Maximum number of users is not a very good indicator of measuring squid
performance. I think, it makes more sense on finding out the maximum
req/sec that a box can handle, keeping the service timers within reasonable
limits.
And, looking a your stats once again, I think you need to upgrade to 64-bit
of your OS to properly use the full 8GB RAM.

On re-reading this whole page, I realise how to estimate the number of
users. I've started graphing the number of cache clients and it looks
like
1200 is a better guess.
