Just another data point (in case anyone's actually collecting this
stuff) - the University of Western Sydney, Nepean's (UWS Nepean) top-level
proxy is the VM version of Squid 1.1.17 (1.1.15 ran for well over a month
non-stop 'til I had the machine rebooted).

The machine is dedicated to running the proxy - absolutely nothing else is
on the box (at the moment anyway); it's a Sun Ultra Enterprise 2 Model
2170 with 512Mb RAM. The cache is spread over six 4.2Gb Fast/Wide SCSI
7,200rpm disks (on their own SCSI adapter). Direct user population being
served is about 13,000 students and 1,200 staff - given that the proxy has
nine siblings at other NSW universities, indirect user population would
have to over 100,000 users.

Memory usage "at this minute" according to "top" is:

last pid: 10450; load averages: 0.18, 0.17, 0.16 09:08:16
47 processes: 45 sleeping, 1 stopped, 1 on cpu
CPU states: 90.5% idle, 2.0% user, 3.5% kernel, 4.0% iowait, 0.0% swap
Memory: 497M real, 8040K free, 387M swap, 1048M free swap

  281 cwis 8 0 370M 326M sleep 23.6H 4.04% 4.40% squid
