Those boxes were Compaq DS10, 1 Alpha CPU (unknown MHz), 512MB mem,
RedHat-6.2 derived OS, 3*9GB 10Krpm cache disks making up an effective
cache space of 20GB, 1*9GB 7.2Krpm system+log disk. Dual UW scsi
controller. Daily 30 minutes average of 150req/s live traffic during
peak hours (9-17, corporate environment). Have not been tested with
polygraph so it is a bit hard to compare figures with other boxes...

It is very much possible that we might have been able to cram a
significantly higher horsepower out of the CPU by selecting a better
compiler and such things, but as the boxes gave good enought performance
we did not bother.

And yes, Squid is so far essentially single-CPU oriented. True SMP
support might appear in Squid-3 which is now only in the very early
planning stages. Before that we will see Squid-2.5 and possibly even
Squid-2.6. and before Squid-2.5, 2.4 must get released.. (testers highly
welcome to test Squid-2.4-HEAD to speed this up)
