Amisu,
Do you get close-to-ideal hit ratio with Squid at much lower
traffic rates (e.g., 30 req/sec)? If yes, then you are probably
overloading Squid and it responds by not caching some of the traffic
to ease the impact of the load. Another possiblity is that Squid does
not have enough disk cache to store all the files (does ISA server
have more storage?).
If you get poor hit ratio regardless of the request rate, then you
most likely have a configuration/compatability problem. Squid should
show nearly ideal hit ratio with PolyMix workloads under normal
conditions.
HTH,
Alex.
