Maybe a dump question: why does it take so long for some TCP_MEM_HITS
to 'show up', for example i got this:

Dec 21 17:37:15  42721 192.X.X.X TCP_MEM_HIT/200 68873 GET http://example.com
Possibly ACL processing needing to wait for something (dns lookup, auth
processing, external acl, ...?)

The time is the time between Squid reading the request and sending the
last piece of the response.

Could also be a slow client (ie dialup modem). 68KB of data at dial speeds of 1-2 KB/sec would take that long. Modern browsers open many concurrent requests, which can drop modem speed down into that range very easily.
