I've been using Comodo Firewall for a few weeks. I thinks it's a fine firewall, with a lot of granular control. But because the classical HIPS Defense + module is still pretty talkative (yes, I've employed some settings to quiet it down), I've decided to give Online Armor a trial. Questions for *objective* folks who've at least tried OA3: Do you find OA3 to perceptably (even minutely) slow down your web browser from resolving pages? Can anyone comment OA vs CFP in terms of the general "responsiveness" of web browsers (surfing)? I've seen a few reports here and there (not the majority, it seems) that boot times are slightly affected. In the context of my situation, I'm running an XP laptop with a Pentium M 2.00GHz Core Duo with 2Gb ram. Many thanks!
