Although I'm not a sysadmin, I'm in the web development business since 1999 as lead developer, and I can safely say there is a problem when your load average is more than 0.20 in normal conditions and swap used shows too something wrong.
so, and assuming SDS posted normal conditions and not peak conditions :
means for me that your CPU is too heavily used
you should have 0 zombie process ; some proccess might have been wrongly terminated
way too much on normal conditions
for me, it's fine
means swap has been used (maybe once, aybe more), and generally it's a bad thing, server didn't have enough RAM, so went into swap (physical disk allocated memory), and then everything runs more slowly and everything become a vicious circle.
under normal conditions (no cron used by the time, no heavy requests on mysql by the time), that's way too much.
that said, SDS said he changed something on mysql (internal stats disabled ?), it could have done the trick.
