Can you tell us about the hardware you're using?  CPU, speed, memory
available and used, OS, Version of OS, etc?

If you have the system performance tools loaded - which didn't appear to be
a default for the RedHat linux's I've installed recently - you can use
combinations of iostat, vmstat, sar, top (which you already know) and
netstat to monitor whats going on with the machine.

My off the cuff guess, based on what you wrote, might be that you're
machines are memory starved and are having to dip into their swap to keep
chugging along. You should be able to see this either with top or with 
"vmstat 5"

A old, but still favorite book about this sort of thing is O'Reiley's
"System performance tuning" AKA "The sailfish book" :
