 If that didn't solve the issue, you can try running the server from the [source](https://github.com/CDeenen/MaterialServer/blob/master/README.md#running-from-the-source).<br>
 Please also [contact me](https://github.com/CDeenen/MaterialDeck#feedback), so I can try to fix the issue in later releases.
 
+## Why does the Stream Deck update so slow?
+The update speed depends on how powerful your computer is. Both the module and Stream Deck plugin need to do quite a lot of calculations in order to change the icons. Even on a decently powerful computer it can take a second to update all buttons.<br>
+You can try increasing the 'Image Buffer Size' in the module settings. This will allow the Stream Deck plugin to store previously sent images. This will prevent your computer from having to scale and convert the same image every time it has to be displayed. I have noticed a performance improvement of about 25%, but this will depend on the speed of your computer.
