Hi Jim,

I used to run a squid proxy for @500 users on a p2-233 with 64mb RAM and I
found the limit there tended to be around 150-175 concurrent connections
before things started slowing down.

I think this is an OS problem rather than a Squid issue directly. I did
find, though, that there's a couple of things you could try to maybe speed
things up. These worked for me, and may not work for you at all :)

1) I stopped using Squid's own DNS resolver and made it use a small
dedicated nameserver box connected via a 100mb link.
2) I moved the cache directory onto a disk with formatted with reiserfs.

This seemed to help a little but, as I said, may have no effect for you.

Good luck :)
