To my experience, heavly loaded Squid boxes run into I/O bottlenecks
faster than anything else (apart from memory maybe, but you have ample
My advice would be: get more disks. A single spindle is just not a
good configuration for Squid, even a fast disk. You didn't mention
whether is it SCSI or IDE. I usually go for SCSI for anything I/O
intensive, although that's more a cultural thing than based on any
hard evidence I've seen.
Don't do RAID. Bring up a filesystem on each disk (with soft updates
of course), mount them "-o noatime" and configure Squid to use
multiple cache dirs.
Sorry if I'm just telling the obvious here. I'm sure someone will come
up with some finer tuning advice.
