Squid-3 has tested well according to some basic speed tests up to
650req/sec at 500/1000/1500 concurrent connections.

I have a i386/ 2.1GHz single-CPU machine doing well. I think Adrians
test were done one a late 2.x GHz machine. Slow stuff by most standards.

Exact details of Adrians tests and hardware should be listed in the mail
archives under benchmarking.

I've only had responses from 3 people outside those of us coding it up.
Two were very happy, one had issues that turned out to be kernel
back-port problems. There has been no confirmed bugs in the squid code
itself. Not bad.
I'm considering moving my production interception machine over to using
it in a few weeks.

I was hoping for initial beta release early this month, but things have
slowed a little. The current 3-HEAD code is fairly stable, only 14 known
bugs. The next features to go in are large enough to cause some upset.
So now is a good time to grab alpha copies if you need them for any
non-testing use.
