What is network latency?

Latency is the speed of traffic on your network. As such, you can’t really speak in terms of ‘good’ or ‘bad’ latency. Acceptable transfer times vary according to the application being used. Video playback and interactive VoIP calls need faster speeds than email delivery. So, you need to work out what speeds you need for your network traffic in terms of the services you provide to your users.

Causes of Network Latency

Measuring latency

Latency is always expressed in milliseconds (ms). However, there are two metrics that express latency. Whichever you choose to use for the tests on your network, try to keep all records in the same test category.

The most common measure of latency is called ‘round trip time’ (RTT). As the name suggests, this is the time it takes for a packet to get from one point on the network to another. The alternative measurement is called ‘time to first byte’ (TTFB). This records the time difference between the moment the first part of a packet left one point on the network and the time that it arrived at the destination. RTT is used more frequently than TTFB because it can be run from one location and doesn’t require special data collection software to be installed on the remote destination.

Using Ping

Every network-connected computer has a free latency testing tool built into the operating system, which is called Ping. This facility works on the Internet Layer protocol, the Internet Control Message Protocol (ICMP). Every network administrator uses Ping and it is a useful tool for a quick check. You don’t need to install any software on the remote computer and you get a report back to the computer from which you launch the command.

A typical Ping execution will send 32 bytes of data to a given destination and record the time that a response arrived back. The latency is expressed as the round trip time that includes both the transfer time for the test packet and the response packet. That time is shown in milliseconds.

You don’t have to know the destination IP address if you are testing the RTT to a website because Ping will accept the domain name as an address instead of the actual IP address. By default, Ping will send out four test packets, but an option on the command enables you to specify a different number of tests.

The results of the Ping command shows the RTT for each test and then summarizes the results. You will see the number of packets sent, the number of responses received, and the number of packets that were lost. You will also see the lost packet tally expressed as a percentage of all tests made. A second summary line shows you the minimum, maximum, and average round trip time for the test batch.

Problems with Ping

Ping is great for a quick investigation when a specific path seems to be running slow. However, the tool isn’t going to help you fix latency problems and it doesn’t allow you to check multiple paths with one command. Fortunately, several more sophisticated Ping-based tools are available. These usually enable you to test multiple paths from the same console. You can also often run a Ping test continually with some tools. These constant Ping tools give a live display on the results of the latency test.

Latency solutions

Latency is a complicated issue that can be managed through traffic-shaping methods, such as queuing algorithms. You can prioritize some traffic with a range of ‘quality of service’ (QoS) methodologies. These enable you to get time-sensitive application traffic through all network devices ahead of all other traffic. This is great if you provide live video delivery of IP telephony apps on your network.

Giving some traffic a clear run through the switches and routers on your network can cause other traffic types to get held up. However, a few minutes of delay in the transfer of an email is a price worth paying if it saves you from replacing your network cable to provide enough bandwidth for all of your traffic to get through at top speed.

The best latency testing tools

There are some great network latency testing tools out there. Many will enable you to test other network conditions as well. For example, jitter is a measure of the variation of the arrival rate of packets in a stream. An irregular pace in the arrival of packets can cause just as many service problems with video streaming and IP telephony as slow delivery.

Another useful metric is the available bandwidth on each stretch of your network – you should keep track of the potential capacity, the median utilization, and the maximum utilization of those links.

This information will enable you to plan for capacity requirements when your business managers ask for new software to run over the network, or to add on new endpoints for increases in staff levels.

Our methodology for selecting a network latency testing tool

We reviewed the market for latency testers and analyzed tools based on the following criteria:

  • A service that can report on delay and jitter
  • A system that also provides availability monitoring
  • Traffic monitoring features
  • Options for on-demand or repetitive and automated latency tests
  • An alerting mechanism for when latency becomes unacceptable
  • A free trial of a paid tool for a cost-free assessment
  • A paid tool that is worth the money or a free tool that is worth installing

With these selection criteria in mind, we arrived at a list of excellent latency testing systems. We made sure to include both free and paid options.

Key Features:

  • Quality of Experience Dashboard: Showcases network response times and latency.
  • SNMP Monitoring: Efficiently tracks network device performance.
  • Network Topology Maps: Visualizes network structure for easier management.

Why do we recommend it?

SolarWinds Network Performance Monitor is the leading network monitoring tool and it provides many tools for automated network supervision. There aren’t many traffic analysis tools in this package because it focuses on network device statuses. However, the tool continuously checks on latency with Ping. The tool also has an on-demand ping facilitiy.

This monitoring tool can keep check on all of your network devices. Most of the monitoring system is informed by the SNMP messaging system. This enables devices to notify the central controller of any performance issues.

The Network Performance Monitor includes latency testing facilities in the Quality of Experience dashboard. This shows network response times and network latency.

The benefit of buying in a complete monitoring system rather than just a latency test utility is that the discovery of slow segments is just the first task – you then have to fix the problem. Data gathered by the Network Performance monitor will help you work out exactly what is causing traffic to be delivered slowly. You can spot which network devices are experiencing errors and which are overloaded.

You will also be able to get information that Ping can’t tell about why your users are experiencing poor response times. Imagine if you get complaints of slow performance at the Help Desk but your Ping time test shows no problem. Slow software delivery is not always the fault of the network. With a full performance monitor, you will be able to identify bottlenecks on paths, congestion on ports, and overloaded CPUs on servers.

If you opt for the SolarWinds Network Bandwidth Analyzer Pack, you can enhance your traffic monitoring capabilities. In this pack, you get the SolarWinds NetFlow Traffic Analyzer as well as the Network Performance Manager. This tool increases information on network activities by examining traffic volumes between network devices.

All of these SolarWinds products install on Windows Server. You can get a 30-day free trial of the Network Performance Monitor, the NetFlow Traffic Analyzer and the Network Bandwidth Analyzer Pack.

For a free network testing tool, give the SolarWinds Flow Tool Bundle a try. This set of tools uses NetFlow v5, which was invented by Cisco Systems. NetFlow captures packet headers as they pass through the router and the system is also capable of compiling aggregated summaries of traffic data directly in the router.

Once you have captured passing packet headers, you can run them through the network again to get a replay of actual events and see how your equipment performance influenced latency. Another feature in the tool pack will generate extra traffic for you so you can test network performance and latency by adding on services or endpoints.

Who is it recommended for?

SolarWinds Network Performance Monitor is ideal for mid-size and large businesses. IT is able to monitor multiple sites and the internet connections between them but its optimum activity is single LAN monitoring.

6. Network Pinger

Network Pinger

Network Pinger is a free tool that runs on Windows. This simple utility has a great-looking interface that is taken up mainly by a display panel for the results of your sweep. That output is a recursive Ping. It will test all destination IP addresses that lie within the range that you enter as a parameter of the search. Side panels show graphical representations of the data collected by the sweep. These include a pie chart of contact status and a line graph that shows response times. You also get to see the RTT (Round Trip Time) for each contact attempt.

Key Features:

  • Recursive Ping: Efficiently tests multiple IP addresses within a specified range.
  • Graphical Representations: Offers visual insights into ping results.
  • Integrated Utilities: Includes Traceroute, Remote Desktop, and other network tools.

Why do we recommend it?

Network Pinger provides the one tool that everyone uses to measure latency: Ping. This is a free tool that has some nice extras that you normally wouldn’t expect without having to pay. It shows graphs of Ping results and it also includes a Traceroute utility. There are a few other extras in this handy free tool.

As well as a Ping function, Network Pinger includes a Traceroute facility that will give you the response times of each hop in a link to a given destination address.

7. ManageEngine Free Ping Tool

ManageEngine Ping and Traceroute

This great ManageEngine utility is actually a Ping and Traceroute tool. The free package also includes a DNS Lookup feature and a specialist measure of response times for websites.

Key Features:

  • DNS Testing: Includes a DNS tester for additional network insights.
  • Web Connection Tester: Evaluates website response times using Ping.
  • Ping and Traceroute: Offers essential network testing functionalities.

Why do we recommend it?

ManageEngine Free Ping Tool is a handy little package that offers Traceroute as well. There are a few other tools in this utility, such as a DNS tester and a Web connection tester, which is also based on Ping. This package is very similar to the Network Pinger but it doesn’t create graphs.

The Ping section of this tool shows each of the given hosts and the Ping data for each, including the round trip time. The screen will keep refreshing giving you live updates on the RTTs to your list of IP addresses.

One problem with the tool is that you have to enter each address individually rather than by entering an address range. However, once you have those entered on the screen, they will stay there even when you have to stop the monitor to switch to other utilities. The Ping results can also be shown on a time series line graph.

The Traceroute utility shows you the round trip time on each hop of a route to a given destination and shows a bar alongside. This makes that RTT easy to understand, highlighting the hops that took the longest to cross.

The DNS lookup utility will refer to your local network DNS server, or the closest internet-based server if no local records exist for the URLs that you enter. You can enter either an IP address or a URL as the search term for this utility.

The Web Response tab gives you a nice graph of the response time to the Web server for a given website address. This graph will continue to update and it shows you the RTT broken down between TCP session establishment, redirection time, and web page response time.

This is a great little tool and you can also get reports printed from it in PDF format, which you can save or email.

Who is it recommended for?

This is the same Ping function that you can access within OpManager, so if you are only interested in measuring latency and not using the device monitoring functions of OpManager, get this tool instead. This system is only available for Windows, so you need to find something else if you only run Linux.

Pros:

  • User-Friendly: Simplifies testing for non-technical users with an intuitive interface.
  • Versatile Testing: Effective for on-site tests and smaller network environments.
  • Portable Deployment: Can be easily used from a thumb drive for convenience.

Cons:

  • Limited Enterprise Use: Not suitable for extensive, long-term network monitoring.

8. PingPlotter

PingPlotter

PingPlotter is available in three editions: Free, Standard, and Professional. The free version is actually a 14-day free trial of the Professional edition. All versions of the tool implement Ping and Traceroute, giving results of both tests in graphical format.

Key Features:

  • Multiple Editions: Offers Free, Standard, and Professional versions.
  • Continuous Testing: Allows ongoing ping to a target for real-time monitoring.
  • Tabbed Interface: Facilitates simultaneous monitoring of multiple sessions.

Why do we recommend it?

PingPlotter provides Ping and Traceroute in combination to give you a range of connection testing utilities that display latency per link and end-to-end between two points. This system is available for installation on Windows, macOS, and iOS, so it can be used to test wireless networks as well as LANs. There is also a cloud-based service.

The console for the tool has a tabbed display panel, much like a Web browser. For each target, you start a new tab, which shows a list of the hops between your computer and the destination. Tests keep running live and accumulated results for the latency on each hop is shown in three data columns. These show the average, minimum, and current round-trip times for that hop.

A visualization column at the end of each row plots the minimum, maximum, and average RTT on a line. A vertical line graph runs along all of the records in the display which plots the current RTT for all hops. A lower panel in the main screen shows both the latency and jitter for the current connection over time. A summary tab shows you latency results for all currently open network connections in the test system.

This is a great tool that will install on Windows, iOS, and Mac OS. The free version only stores the history for 10 minutes, but the two paid versions show data transmission over an unlimited time frame. The paid versions also include an alerting system and you can choose to run TCP or UDP Ping tests – only ICMP Ping is available with the free edition.

Who is it recommended for?

PingPlotter isn’t a free tool but it does more or less the same as the free tool from ManageEngine and PingPlotter. However, there is an advantage to this tool in that it provides a path view for its Traceroute tests, which those rival systems don’t offer.

Pros:

  • Versatile Versions: Provides options for different user needs, including a free version.
  • Graphical Latency Insights: Offers visual representation of latency across devices.
  • Continuous and One-Off Testing: Suitable for various testing scenarios.

Cons:

  • Limited Trial Features: Some functionalities like TCP/UDP tests are not available in the free version.

9. NirSoft NetworkLatencyView

NetworkLatencyView

The NetworkLatencyView tool from NirSoft is a little different than all of the other latency testers on this list. Rather than examining links to a given destination, the utility listens for all new TCP connections and monitors while they persist. This system doesn’t issue Ping tests. It extracts packet latency information from live packets passing along the network and operates at the Transport Layer.

Key Features:

  • TCP Connection Monitoring: Observe new TCP connections for latency data.
  • Non-Ping Methodology: Extracts latency info from live traffic, not using Ping.

Why do we recommend it?

NirSoft NetworkLatencyView has a surprising technique for a small free tool. It doesn’t use Ping to test a path between to points, but it listens to existing traffic and derives latency data from that. This is a sophisticated method that addresses the main problem that network administrators have with Ping, which is that it doesn’t actually show traffic speeds.

This is a free tool and it installs on Windows. The display window can show up to 10 Ping test RTT values for each detected network connection. It also shows the average of those ten tests. This makes the display area very wide. However, you can resize columns, stretch the window, or scroll to the right to see all of the data. Results can be saved to CSV, HTML, XML, tab delimited, or text file for analysis in other apps.

Who is it recommended for?

This tool shows live traffic speeds rather than the test results of Ping. This is a useful tool for network managers who wonder whether real traffic is actually behaving the same way that packets in a Ping test do. The tool is only available for Windows.

Pros:

  • Innovative Approach: Offers unique insights by monitoring actual traffic rather than simulated tests.
  • Simple Interface: Facilitates quick identification of latency issues.
  • Multiple Export Formats: Allows exporting results in various file types.
  • Platform Limitation: Only available for Windows, not supporting Linux or Mac.

Cons:

  • Basic Interface: Lacks graphical representation and is less suitable for large networks.

10. Angry IP Scanner

Angry IP Scanner

Angry IP Scanner is a free Ping utility that will run on Windows, Linux, and Mac OS. The straightforward layout of the interface makes this a useful tool for busy system administrators. You can start a Ping sweep either by entering ‘from’ and ‘to’ IP addresses or by entering a hostname and a CIDR notation offset. It is also possible to enter a non-consecutive list of IP addresses by loading them into the interface from a file.

Key Features:

  • Cross-Platform Compatibility: Runs on Windows, Linux, and Mac OS.
  • Port Scanning: Includes options to scan for open ports on network devices.
  • Flexible Input: Supports a range of input methods for address specification.

Why do we recommend it?

Angry IP Scanner is a widely-used network tester that, as of March 2023 has more than 29 million downloads. This system offers Network Layer testing with Ping to discover which IP addresses are in use and those results also show the latency on connections to devices that respond. Transport Layer tests are also possible.

The tool will ping every address within the given range and show each in the output. This can result in a lot of unused addresses appearing on the screen. You can avoid this large number of irrelevant records by setting in the Preferences section of the tool that only live IP addresses should be shown. This requirement can be refined further by an option that limits the output list to show just those hosts that have open ports.

Tests can be carried out with the classic ICMP message, with TCP, or with UDP. Although the utility will ping many hosts in one run, it will only run each Ping probe on demand. The service does not repeat continuously. If you want to refresh the report, you will need to push the Start button again.

The default output only shows the average RTT for each discovered IP address along with the hostname of that destination and the number of open ports on that device.  You can customize the output screen by selecting extra data categories. These include a Packet Loss field.

The number of tests issued is dictated by one of the settings in the Preferences screen. The default number of probes is three per address. The output of a test can be exported in CSV, XML, text or IP-Port format.

Who is it recommended for?

As it is free to use, this tool is suitable for use by any network manager for a quick scan of the network. However, it is more likely to appeal to small businesses that don’t already have a full network management package to scan for IP addresses. The system is available for Windows, macOS, and Linux.

Pros:

  • Wide Accessibility: Useful across different operating systems.
  • Export Flexibility: Allows exporting results in multiple formats.
  • User-Friendly: Simplifies network scanning for technical and non-technical users.

Cons:

  • Enterprise Limitations: Not ideal for monitoring large-scale enterprise networks.
  • No Graphing Tools: Lacks advanced visualization capabilities for network analysis.

11. Pinkie

Pinkie

Pinkie is a suite of network monitoring tools that includes a Ping sweep option. The tool is free to use and will run on Windows.

Key Features:

  • Bundled Network Tools: Includes a suite of network monitoring utilities.
  • Range-Based Ping Sweep: Tests a range of IP addresses efficiently.
  • Additional Network Functions: Offers port scanning, subnet calculation, and more.

Why do we recommend it?

Pinkie is similar to Network Pinger and the ManageEngine Free Ping tool because its interface offers a range of connection testing tools in addition to Ping. The system provides you with Traceroute as well so, you can check on the latency of each link in a path to a destination.

The tool also includes a straightforward Ping option, which will probe just one destination IP address, which can also be entered as a URL. This feature will continue to issue Ping packets to the target, showing the RTT and also the ‘time to live’ setting entered in each probe packet.

The Ping Sweep option will test a range of addresses. However, the test is not continuous and you have to relaunch the utility by pressing a Start Ping Sweep button to get the results refreshed. A checkbox in the search section of the screen enables you to exclude IP addresses that are not live. The results in this screen show the IP address, the hostname, and the RTT of that probe. The Ping Sweep output can be copied to the clipboard and then pasted into a text file.

Other utilities in Pinkie are a port scanner, a Traceroute implementation, a DNS lookup function, and a bulk DNS reference facility, which uses a list of addresses from a file. There is also a subnet calculator and a TFTP server in the bundle. This is a very useful pack of tools that help you keep all of the facilities you need to check on your entire network in one interface.

Who is it recommended for?

This is another option for small businesses because it is free to use. Its extra utilities are nice to have on hand. Those extras make this package more useful than Angry IP Scanner. However, unlike that rival free tool, Pinkie is not available for macOS or Linux – only Windows.

Pros:

  • Comprehensive Toolset: Provides various essential network tools in one package.
  • Free Utility: Accessible without cost, beneficial for small businesses or home use.
  • Diverse Capabilities: Supports external domain and server address finding.

Cons:

  • Limited Interface Design: The interface can be clunky and less intuitive.
  • No Advanced Reporting: Lacks extensive reporting options and graphical tracking.

12. NetScan Tools

NetScan Tools

NetScan Tools Basic Edition is a free set of network testing tools that runs on Windows. The tool is free because it is supported by advertisements. If you want to get rid of those ads, you can buy NetScan Tools Pro. You get three Ping-based utilities in both editions of NetScan Tools. The package also includes a Traceroute facility, so you have four ways to test the latency of your network.

Key Features:

  • Ad-Supported Free Version: Offers essential network tools with advertisement support.
  • Graphical Ping Options: Visualizes Ping results for easier interpretation.
  • Traceroute Functionality: Provides detailed insights into network path latency.

Why do we recommend it?

NetScan Tools Basic Edition, like Pinkie and Network Pinger, offers both Ping and Traceroute. There is a graphics-based Ping option and you also get DNS resolution. The package includes a Whois query tool and you can also check on DNS server records. Discover devices and check on transfer speeds with this tool.

The first of your Ping options is a straightforward graphical interpretation of the standard command. You enter a domain name, a hostname, or an IP address and the tool will send out five Ping probes to that destination. The output will show the RTT and time to live of each probe. You can alter the number of network packets sent in each run in the Settings menu.

A Graphical Ping option shows a constantly-executed Ping test to a single destination. Again, that target can be specified by hostname, domain name, or IP address. The test will keep repeating until you choose to stop it – even continuing when you move away from this screen to try a different utility. The line of the graph shows the RTT of each attempt.

A Ping Scanner lets you test a range of IP addresses. The output will show the results of a Ping test to every address within the given range. However, you can select to cut out non-responding addresses. The results include the IP address, the hostname, the round trip time, and a status report for each address in the range. A context menu on this screen is available when you click on the right mouse button. This enables you to print the output of the test or save it to a file.

The Traceroute tool gives you another view on your network latency. This shows every hop between your computer and a given destination address. The RTT of each hop is shown alongside the IP and address of each intermediate router. This command will run once. You have to reissue the command if you want to get an update on the speeds of each link in the connection.

Other tools in the pack are a DNS lookup feature and a Whois query tool.

Who is it recommended for?

This is a free tool that displays ads. You can pay for the Pro version to get rid of the adverts. The graphical Ping option is a nice rival to Network Pinger. This system is only available for Windows, so if you run macOS or Linux, you should go for Angry IP Scanner instead.

Pros:

  • Versatile Budget Options: Accessible for any budget with free and paid versions.
  • Lightweight Application: Can be run on a wide range of endpoints.
  • DNS and Whois Tools: Enhances network testing with additional query capabilities.

Cons:

  • Outdated Interface: The interface may feel cluttered, especially on larger networks.
  • Windows-Only: Limits its use to Windows operating systems, excluding Mac and Linux users.

Choosing network latency test tools

Although there are many different methods for measuring latency on your network and across the internet, Ping is the most commonly used utility to test connection speeds. As you can see from our list of options for testing latency, all companies producing network monitoring tools for speed tests make sure to include a Ping tool in their applications.

In this guide, you have read about ten alternative tools that will provide you with latency testing facilities. Your first task, when narrowing down this list, is to examine the operating systems that each option will run on and only focus on those that run on the system on which you want to run your monitoring facilities. Fortunately, all of the latency monitoring tools on our list either have a free version, a free trial, or are completely free to use. Many of the tools are very lightweight and don’t take up much disk space, so you can download a few of them to compare their performance.

How to Test for Network Latency FAQs

What is latency in the cloud?

Cloud latency is the time that passes between a client issuing a request and a cloud service launching a response. As the path from a client to a cloud server involves the public medium of the internet, the issue of latency in the cloud is difficult to resolve.

How do I locate WAN latency issues?

WAN latency involves measuring transmissions over three networks: the home network, the remote network, and the linking network, which could be a fixed link but is usually the internet. Network administrators have greater control over the business-owned networks wherever they are located. Identify the cause of WAN latency by testing in-house network speeds first. If they are working at peak performance, the internet link is the cause of your transmission delays.

What is application latency?

Network latency examines the speed of transmission between devices. Application latency adds on an examination of the speed of delivery of a service within the server and the processing ability of the receiving endpoint.

Can network mapping spot latency?

Network mapping is a monitoring and management tool. A straightforward network topology map is a picture, which can help administrators to spot possible bottlenecks just by working out how much traffic needs to run along each link. However, monitoring tools add live traffic data to the diagram. Accumulating actual traffic flow data is the most accurate way to identify overloaded devices and links and that leads to more effective capacity planning and traffic shaping strategies.
