Hi there,
I am running squid 2.5 on freebsd 7,
As Adrian said, upgrade. 2.6 (and 2.7) support kqueue under FreeBSD.
and my squid box respond very slow during peak hours. my squid machine have twin dual core processors, 4 ram and following hdds.

below are the status and settings i have done. i need further guidance to improve the box.

Those statistics show wildly different utilization. The first (top, I
assume) shows 75% idle (or a whole CPU in use). The next two show 95%
idle (in effect, one CPU 20% used). How close (in time) were the
statistics gathered?

if anyother info required, i shall provide.
The types (and number) of ACLs in use would be of interest as well.
