One thought to resolve the single threading of Squid, use a virtual
machine software/system like VMware. The virtual machine software
would handle the processor allocation. The separate virtual machined
Squid servers could run a in a shared cache setup. I'm considering the
virtual machining of my Squid servers. My RH AS 3.1 Squid server on a
Dell PE 1650 (1.13 GHz PIII) is only using 10 - 15 percent load for 750
users.. I could run two or three virtual machined server instances and
get 60 to 80 percent load. The idea is to get a higher ROI for the
server hardware.
I suspect even with your 3000 users, you will only get a 30 to 40
percent CPU load on the dual XEON boxes.
