Our performance is not what I think it should be. And after awhile it slows down. I am running Redhat 8 Intell P3 server with 1gig Ram I am running Squid Version 2.5.Stable5 with options ./configure --enable-storio=diskd,ufs --enable-gnurex We have on average between 250 and 500 connections to the internet at one time durring school hours. We have one full (not a fractional) T1 line to our ISP. We are using a 2500 Watchguard Firewall and the squid box is sitting on a (DMZ or optional side of the firewall) The clients hit the firewall and the firewall sends the http traffic to the squid box.
