The two biggest considerations for Squid boxes are RAM and disks, because Squid will generally bottleneck there first. 1) Size your RAM based on the guidelines in the this FAQ http://www.squid-cache.org/Doc/FAQ/FAQ-8.html#ss8.11 2) Get the fastest disks you can afford - SCSI preferred over IDE. Ideally, dedicate a physical disk to just the Squid cache. Squid's cache does not benefit from RAID, and some types (RAID 5 in particular) will kill disk performance. > I read on squid site that squid does not benefit from > a dual box. What have you guys notice in the field. Squid itself does not benefit from a dual-CPU setup. However, one CPU can be running Squid while the other CPU runs the async-IO programs, Squid helpers, and processes from other parts of the system, so there is some benefit to a multi-CPU system. However, RAM and fast SCSI disks will give you the most benefit for cost. Adam
