Speaking of 40% rates being "wierd" or "nice", you're going to *hate*
this; but our averages are 40-50% (50+% on the odd occasion, record is
well over 60% one weekend) on requests alone, 30-40% for traffic (TCP

Our cache is only a midget at 1.3Gb. :-)

We found "tuning" of ttl's (after watching the most hit sites/URLs in the
daily stats) to do wonders for the hit rates. The number one site through
our main proxy is "home.netscape.com" (surprise, surprise), with a 98+%
cache traffic hit rate (TCP bytes).
