What OS?
What Squid version? (STABLE1 is not a Squid version.. 2.5.STABLE1 is)
What tuning have you applied to TCP/IP for high rate proxies? Most OS:es
needs to be slightly tuned in their TCP/IP to handle above ca
100-150req/s.
Are you caching? If so, how is your cache directories configured (number
of drives, drive configuration, filesystem, cache_dir type etc)
