How to fix Kodi running slow

Is your Kodi installation really slow? Are you trying to make Kodi faster? In this guide, we’ll identify the factors that might cause your Kodi app to run slowly and show you how to resolve them. There’s also a special deal for our readers at the end of this article.

Kodi is free, open source software that makes it easy to quickly set up your own home theater system. It’s highly versatile and can be installed on a wide range of platforms including PC (Windows, Mac, and Linux), Amazon Fire TV, Firestick, Android, iPhone, Roku, Raspberry Pi, Apple TV, and even USB flash drive.

While Kodi is easy to set up, it can be difficult to find the root of some problems that occur. One of the most common issues Kodi users encounter is app slowdowns and lagging. This can happen when trying to connect to media, or in some cases, just when navigating the menus. In this article, we’ll be showing you how to find the root of the Kodi problems and correct them. This should make your Kodi software faster than ever and allow you to use Kodi as it was originally intended.

Why is Kodi running slowly?

There are several different reasons that your Kodi installation could be running slowly. We’ll start by addressing some of the more common issues so that we can quickly isolate the cause.

Network problems

If you’re finding that Kodi loads content slowly or in short bursts, it’s likely that the cause is a problem with your internet connection. Firstly, get everyone in your household to stop using the internet and run a network speed test. This will show you your network’s average upload and download speeds across a short period of time.

The upload speed doesn’t matter when streaming video, but you should pay attention to your download speed. Netflix recommends a speed of at least 3 megabits per second (Mbps) for standard definition content, 5Mbps for HD content, and 25 Mbps for 4K content. If you find that your speeds are lower than what your internet service provider (ISP) claims you’ll receive, try using a wired connection or moving closer to the router, then run the test again to see if they improve. It’s also worth noting that network repeaters or extenders can reduce the speed of your connection, so try connecting to the original network instead of the strengthened one.

If your internet speeds are as advertised, you have two options: either pay for a broadband package with faster network speeds or reduce the quality of the video you watch. Try playing a YouTube video at 360p to see if it loads properly. Even the slowest internet connections should manage to buffer this almost immediately.

If you’ve tried the steps above and your internet speed hasn’t improved, try turning your router off, waiting a few minutes, and turning it back on. This is one of the easiest ways to resolve common network issues. Next, try watching content from a different provider. If this content loads quickly, that’s a sign that the original provider may be experiencing heavy traffic. If both providers load slowly, make a note of this. There might be a service disruption or hardware issue on your ISP’s end that they can address should our other fixes fail.

Kodi configuration problems

Even though Kodi can be installed on many different platforms, not every device on each platform has the same specifications. For instance, some Android cell phones are less powerful than others. If your buffer size is too large or your cache size is too small, this can lead to a significant slowdown on your device. Luckily, there’s a way to optimize Kodi’s settings to better accommodate your device’s hardware.

How to speed up your Kodi installation

The tips above should have given you an idea as to the root cause of your slowdown problem so all that remains is to rectify it. Network problems are more difficult to address since you have a limited amount of control, but beyond extending your wifi router range or paying for more bandwidth from your ISP, configuration or cache issues can be resolved in just a couple of minutes.

Configuring Kodi for your device

Firstly, you’ll have to install the Ares Wizard Kodi addon. It takes a few seconds to open, but once it does, click the Tweaks option at the top of the screen. You’ll see a menu on the left-hand side – click Advanced Settings Wizard.

Ares Wizard will tell you what a cache is and analyze your system. Once this is done, it will recommend a cache size based on your device’s hardware. Click on the Generate settings button at the bottom of the page. You’ll see your device’s recommended cache size, CURL timeout, and read buffer factor. Click on the Apply these settings button, restart Kodi, and try to load a video. This will allow you to see if the system optimization resolved your slowdown issue.

Clearing Kodi’s cache

A cache is a collection of previously accessed data. If there are certain pieces of information that are frequently needed, it makes sense to store them somewhere convenient for faster access. Problems can arise when the cache is full (meaning slow access to important files) or when software is updated but still relies on older, cached files. Clearing the cache can help in these cases, and doing this on Kodi is fairly simple.

When you stream video through Kodi regularly, a cache of data is stored on your computer. That cache can get filled rather quickly, leading to buffering issues and other slowdowns for your Kodi app.

To clear your cache, open up the Ares Wizard addon. From the main screen, click the Maintenance tab at the top. Next, click the Delete Cache\Temp button in the Cache section. A window will appear telling you how many files were deleted. Now close Kodi, reopen it and try streaming video again to see if this helped.

Using a VPN to avoid ISP throttling

It’s sad but true: many ISPs intentionally limit the network speeds of their paying customers. They do this to discourage people from streaming video online, but don’t take into account those who only stream from official sources. Worse, in some cases, they actively target customers who use legitimate streaming platforms. They do this by analyzing their users’ network traffic and automatically capping network speeds based on traffic patterns.

When you use a virtual private network (VPN), all of your incoming and outgoing traffic is encrypted. This obscures it and makes it impossible for your ISP to track your activities. With no way of telling what you’re doing, your ISP is far less likely to automatically reduce your network speeds. This can prevent the endless buffering,  that happens when trying to stream video on a slow connection.

Of course, it’s important to choose a VPN that can be trusted to maintain your privacy. Several free VPN services have been found to include malware, and Hola, a popular free VPN, was caught selling its users’ bandwidth for use in botnets.

We recommend using IPVanish. Unlike most other VPN providers, IPVanish builds and maintains its own server infrastructure. This means that it provides some of the fastest, most stable connections available. With servers in more than 50 countries, region-locked content stops being a problem for Kodi users.

IPVanish takes their customers’ privacy very seriously. They keep no records of their users’ traffic history so you’re completely protected from ISP snooping. It’s also one of the most portable VPN services with dedicated software for Windows, Mac, Linux, Android, iOS, and the Amazon Firestick.

BEST VPN FOR KODI:IPVanish is our top choice. Has a large uncongested network of servers and achieves good speeds. Strong security and privacy features make IPVanish a favorite for Kodi and Amazon Fire TV Stick users. Try it risk-free with the 7-day money back guarantee.


There are several reasons why Kodi might be running slowly for you. The good news is that because Kodi is designed to be run on so many devices, it has very low system requirements. This means that you should never have to upgrade your system to use Kodi. Instead, the problems are likely to be far more easily resolved. By following the steps laid out above, you should be able to fix any Kodi slowdown issues and get back to watching content how it was supposed to be seen: in the highest possible quality, with no stuttering.
