2/3 of time is system time. is it OK? can squid be made faster. it's using
diskd, disks are much less loaded than CPU
Which version of Squid are you using? Whats the request rate at the time
Squid is using that much CPU? Whats the hardware spec?
FreeBSD 6.2, pentium 4 2GB RAM (but RAM is more than enough), 2 squid
disks, 3 directories.
request rate - will have to check when traffic is highest (somewhat like
50-100), 850 people network,

SMP turned off, most FreeBSD users advice Hyperthreading works best
when... unused but i can try SMP.

very complicated) below:

disk load are like 20%, CPU like 50% under highest load, system disk are
separate.
