We're running a standard (VM) version of squid on a less powerful box than
yours, and it's handling 400,000 TCP queries a day with little apparent
strain. Ours is an Alpha server 200/255 with 4Gb disk and 128Mb of RAM.
The only slight difference is that our 4GB is split between two RZ29s,
each of which is partitioned in half. I'm planning to use all four
partitions (our LRU time is down to about 24 hours, which is silly, but
the hit rate is still 50% or so) once I can persuade someone to buy me
more memory. If I can find a *really* generous benefactor, I'm hoping to
upgrade to fast-wide SCSI one day.

We've had no problems with the standard out-of-the-box setup, but if
you've had good results with something different, then probably stick with
