Are you using PERC2/3 hardware RAID?
I found on the similar machines we run here that the hardware RAID
performance under Linux is outrageously poor. I converted all our
machines to software raid and the performance improved from about 15MB/s
write on a RAID5 to 75MB/s with s/w RAID. That's with 10k SCSI drives.
Before the change, our Squid proxies spent an awful lot of time being
I/O bound.
Also, I split the cache into 3 cache dirs, each 8GB on a different
physical drive. Now Squid is a very happy bunny.
