Will a Pentium III-500 do as firewall?
Posted on 2005-03-29
We have a small network of about 8 machines, one webserver, low traffic. The new webserver (P4-2.4GHz) works quite fast from the inside. Pages normally display in less than 1 second. From the outside it takes up to 5 seconds. Typically nothing happens for about 3 or 4 seconds, and then suddenly the page appears. When inside, visiting other websites, we have a normal speed.
The firewall/router is an old Pentium III-500 (320MB) machine running Windows 2000 and Isa Server 2000. (Memory usage is about 150MB.) Can this be the bottleneck? I heard that a 486 could be used as firewall. Are there tools to test what causes the delay? Is a Linux firewall faster? Or a hardware firewall?
