Our servers are dual pentium pro/200 with 512MB Ram in each server. The
limitation of 300 is pretty close. We run around 600 clients (we have never
seen more than 300 clients running concurrently) on each server as we do not
fully take advantage of load balancing. The second server is primarily used for
redundancy. As far as my comments regarding the proxy cache crashing the
server, this was an NT problem. Upgrading to IIS v4 seems to have resolved the
issue. As an aside, IIS v4 also gives much better error descriptions.
Hope this helps.

What kind of server are you running that on? Dual proc/quad proc? RAM? I
was told the typical limitation to a single MS proxy server is something
around 300 concurrent connections. Do you feel this is relatively
accurate?
