>I used top and the system was not bottlenecking. Top only checks CPU usage - and Squid (like most servers on modern hardware) will usually bottleneck on CPU last.
I suggested procinfo, vmstat, and sar because they give you info on memory, disk, and CPU - and Squid will tend to bottleneck on disk before anything else. Also, you mentioned that the Squid server had 6 36-GB SCSI disks - are you using any sort of RAID? Adam
