I never roboot the server(except for a power failure) but restart squid
regularly instead (once a week). I have to do this since there was a bug
in older squid that cause it constantly grow in memory. Since then, I
never remove a restart cron from my crontab. If you think that your squid
process is too big (memory leak or something) restart will help you.

My server takes not more than 5 mins to restart if it was shut down
cleanly. Tom, are you shutdown squid before restart? A simplest way is to
send a TERM signal to squid process and wait until it terminate. If you
start from RunCache, it will restart squid in 10 seconds.
