I've had a peak throughput of 197 hits/sec (average over an 1-hour period,
so the actual peak is higher). Hardware specs:
dual PIII/450
1 Gb RAM
6 9.1Gb (not sure about RPM, might even be 7.2k) Ultra2-wide spindles,
        1 for system, 5 for diskd-based (10 cache_dirs) cache on ext2
AMI MegaRaid controller used as JBOD.
2x eepro100 NICs with Intel drivers on Nortel switches

SW configuration:
Linux-2.2.19
Squid-2.4DEVEL3-NTLM
512Mb mem_cache

Only concession, a significant percentage of the requests are for
NTLM authentication, thus serviced very fast. On the downside, I
have a few 1500+-users ACLs and a fairly complex authorization
scheme (not extreme, but complex).

BTW: Hans Reiser has been bashing squid on the Linux kernel mailing list
today. He has some points, but he is blunt as he is known to be in
expressing himself.
