I'm a network admin for a high school and I have just installed a proxy server program called software 602 on an old server (Dell powerEdge 400) It has 500 mb ram and a pentium III processor. It works quite well to block internet sites but it slows the internet waaay down. I actually have this server between the internet and the entire school but I've only configured the student profile to use it as a proxy server. No one else's internet is slowed down by simply passing through this server, only those using it to filter internet access. Is there any way around this or do proxy servers always slow the internet down?
