Ah.. yes.. the third cache which show only 3% CPU usage has squid v2.6. Is this drop in cpu usage due to changes in v2.6?? I'll definitely want to upgrade to 2.6 now. and one more, what is epoll about ?? configure help only says "enable epoll() instead of poll() or select(), epoll() is best where avialable". what does that mean ?? Thanks alot for your response adrian. I'll soon be planing the upgrade of the squids from 2.5 to 2.6.
