Do you have any idea about how many page hit would handle one squid
servers?
Thinking about a Dual QuadCore 4Gb RAM serving only small files (less
than 300 Kb each).
Adrian has mapped Squid 2.7 as far as 800-850 req/sec. Squid-3 is
untested but expected to be at minimum 500 req/sec (2.5 was capable of
this around the time of the Squid-3 branch).
NP: that is on single-threaded machines.
We have confirmed data from one Squid-2.7 install doing 2.7K req/sec
on high-end quad-core hardware a few years back and unconfirmed
reports of another deployment (unknown version) topping 5K req/sec 1-2
years ago.
Wikimedia are the poster deployment for CARP deployment to around ~200
Squid last I heard and push dozens of TB per day (their network
diagrams show 3 load balancing Squid, I'm not sure if thats right
though). So even if one Squid can't handle it the model scales
enormously.
Their case-study has graphs from back when it was 50 Squid show 560+
req/sec ...

Chris Robertson had some numbers a while back, he may chime in with
something more accurate :)
I'm running a strictly forward proxy setup, which puts an entirely
different load on the system. It's also a pretty low load (peaks of 160
req/sec at 25mbit/sec).
