Do not forget (although this may be obvious), any OS worth its salt will
cache the disc in memory. If you have a lot of memory - is it all being used?
If so then Squid will be using some for its own small memory cache (as
Henrik described) and its general housekeeping indexing of the disc cache,
but the rest should be used by the OS for buffering disc.

This may not be optimum solution (ie squid manages raw memory and disk), but
it is not too bad.
