Thanks for all of the suggestions. Here is where I am so far:


A pointed question: on the server which uses more CPU, how much CPU is spent in kernel mode, as opposed to the user mode? Have you tried doing something like sar -u 3 20? If you have, can you post the result? You can also check sar history files in the /var/log/sa directory.
