Hi there I have a Plesk server running on Fedora 2 and I think it's a great system. However, recently it seems to be slowing down and I'm getting compliants from users etc. Sometimes the websites fly, other times they go really slow. I've monitored the server using the top command and the CPU is always around 1% usage, as there's not much running on it at the moment. I can ping www.google.co.uk from the server and get response times of around 2ms... Can anyone give me some pointers on how to debug and resolve this issue?
