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.

I just got a new HP DL380 server in my hands. I need to replace a older
HP DL360 server that runs squid for about 2500-3000 clients.
This box will have raid1 for system and then 4 extra disks for cacheing
(standalone, not raid).
It also has 2 processors (3.4Ghz Xeon / Hyperthreading) and 4Gb of
memory.
I was wondering ...Should i have hyperthreading enabled or not? I've
been reading along somewhere that some people say that hyperthreading
does not work very good with squid ...any hints about this ;)?
I wouldn't see why it shouldn't work with HT. We had DL360 running our
proxy cluster on (until we were fed up because every now and then the power
unit's fans b0rked) without trouble. Currently we are running on DL580 with
Dual-Xeon and enabled HT.
It will probably not help you much since one process (squid) will not be
able to run on more than one CPU. So unless you have more than process
running on that server one CPU is enough. In our case we run power-hungry
content filters on that box, too. So it helps us.
Kind Regards
