MySQL is one of the most important programs on a server, unfortunately it is also pretty resource intensive. One a  server it is not uncommon for a single user or even a query to take up the bulk of the servers CPU cycles. Mytop is a very useful program to see what queries a server is currently processing as well as which user is executing them. Think of mytop as top for mysql. If you see a lot from a user that means they are probably the hog. Mytop can also be useful for figuring out exactly which queries are causing the problem in the case of a self-designed website.

The following commands use  how to install mytop on the server and run it.
