[squid-users] Questions on object access

I noticed in my Squid (v2.4S1 with all posted patches applied) access.log
this line which raises a few questions:

997671159.285 482 192.168.0.3 TCP_MEM_HIT/200 112615 GET
http://www.geekazoids.net/~images/anotherpriceless.jpg - NONE/- image/jpeg9

The questions:

1. Why is this a TCP_MEM_HIT given that I have this line in my config:
"maximum_object_size_in_memory 64 KB"? Shouldn't a 112KB file be
precluded from being found in memory given that it exceeds the specified
64KB limit?

2. It took 482 milliseconds to retrieve this file from the memory cache.
Is this reasonable for a Linux (RedHat v7.1, kernel v2.4.8) box running on
a Pentium3/550 CPU? (With 100Mbps networking, if it matters.) Maybe my
expectations are unrealistic. but I would think that an object retrieval
that requires no I/O would be faster than 232KB/sec.

Thanks.
