Do you plan to use Squid to cache traffic coming from outside destined
to your own servers, or traffic from inside which is going to outside
hosts?

If you're planning to cache outside traffic coming in, how big is your
website?  How many files, how many big files, etc?

If you're planning to cache traffic going out to arbitrary sites - I
have 50 configured, 42-45 live dual processor dual core 2 GHz Opteron
Linux boxes and can do around 550 URLs/sec per server of external
traffic in test and do 350 URLs/sec during peak periods in production
across the farm, with 50% cache hit rates.  If the URLs are 100k each
on average then that's around 440 megabits.  The servers have 4 disks
- one root, one squid logs, two squid cache, with AUFS caches on the
two cache disks.  4 GB RAM.
