Title: Recommendations for Squid proxy hardware

What would you recommend for Squid proxy hardware, for a machine thats running transparent and has approximately up to 80 dialups pumping requests through it?

Current machine has a drive setup of:

Filesystem            Size  Used Avail Use% Mounted on
/dev/sda1             288M  220M   54M  80% /
/dev/sda3             7.8G  5.4G  2.0G  73% /var/spool/squid1
/dev/sdb              8.2G  2.1G  5.6G  28% /var/spool/squid2
/dev/hdc              9.2G  6.1G  2.7G  69% /var/spool/squid3
/dev/hda1             9.2G  6.1G  2.7G  69% /var/spool/squid4

hdc and hda1 being UATA, rest being Ultra Wide, have installed 256 MB Ram, after around 24 hours all RAM and all swap is taken up and needs restarting.

What hardware do you recommend? currently running a PIII 450, does Squid and Debian take advantage of a Dual processor unit? any other suggestions on making this machine more reliable and efficient appreciated.

Thanks
