hmmm, i've read that. i don't by the way,
however, nothing bad has yet happened, mem utilization seems ok, cache
hits are up. but it's only been a few days.

the machine this is sitting in front of went from 200% to 50% cpu load,
which was the ultimate goal, so life is good so far. it's darn fine
perky. i almost feel like setting up a bunch of cache machines just for
the fun of it.

the most disappointing thing is the CPU load on the cache server, it
hovers around zero (0). once i noticed it was at .2 (20%) and thought
something was about to happen, but it dropped down to zero again pretty
quick. it's rather like having a server that doesn't actually do
anything, and you want to load it up with some email servers or database
or something just so it feels better.
maybe i'll add another site, which receives much more traffic and see
what happens.

I recomment using heap removal policy, even if it's heap lru - it's still
faster than pure LRU
ok, i'll check that out, thanks for the suggestion - i appreciate it.
