[squid-users] Does Squid scale well?

[rihad]

Can someone please say how well Squid 3.1/tproxy scales? Would it have 
problems servicing more than 10k simultaneous HTTP requests, and pushing 
as much as 300 mbit/s of traffic? 500 mbit/s? 1 gbit/s?

Planned hardware & setup:

Dell Poweredge 6850 server QUAD Dual Core 3.4GHz 8GB

Hard Drives:    

cache_dir will be split across
5x 73GB SAS 15K hard drives


All will run on Ubuntu 9.04/testing mix w/ WCCPv1.


Thanks in advance.
