General Trouble Shooting
Sometimes computer problems can feel like James Joyce's dying woman- you know something is wrong, but you have no idea where or how to start looking for it. This article offers help for that.

I'll be covering some general performance related issues here, but the main focus is for the system that was running fine yesterday but is sucking mud today. The typical response to such problems is "Reboot it", and while that may indeed fix the problem, it does not address the root cause, so you are likely to have the situation again.
