    Incidentally, how much space are you dedicating to your Squid cache? I
    know that this can't be assigned directly, so either the segment size,
    or net use (du -s on cache) would be useful.

    Peace.

    A gigabyte does pretty nicely for my users.

    Currently (offline) /var/spool/squid is 109340kB; /var is a 1.25GB
    partition with just over 1GB free. I've set up a script to run
    while [ I'm online ]; do sleep 30; du -sk /var/spool/squid; done
    into a log file, and I'll send you a summary of the results (or
    the whole thing if you want :-) ) offlist once it's aculated a
    reasonable amount of data. Most times I connect, however, I'm only
    on for a couple of minutes and only visit one or two sites and fetch
    mail, so it might be a while before I've done enough lengthy browsing
    sessions to produce useful data.

    As far as memory usage goes, I haven't played with the settings (yet),
    so they're all at their default installation values (cache_mem 8MB,
    etc.) The machine Squid's on at the moment has 128MB RAM and 0.75GB
    swap, so I might find it worthwhile to bump some of the settings up a
    bit.
