Pfsense with UTM features
-
As of right now our Pfsense box is an old P3 750 with 768 megs of ram with Intel Pro 1000MT nics it serves up a 100meg x 5meg connection and it is fast. However, I am wanting to look into virus scanning if I do that I will need more power so my choices are P4 3.2 Hyperthreaded with 3 to 4 gigs of ram or a cor2duo 2.1 with 4 gigs of ram both are using Intel Pro 1000PT nics. My concern with any UTM feature is speed I've always heard stories that when you enable virus scanning your overall speeds tank. So what type of speeds should I expect when enabling virus scans on Pfsense?
