I recently switched from OA premo to Pf, namely because new Sandboxed (Sandboxie), Ff browsing sessions would not load homepage MSN for 15+ seconds on an XP desktop. It is a well documented issue! Now with Pf, sessions start in about six seconds. However, I've noticed that memory usage now is going over 100,000kbs shile browsing, where previously it rarely surpassed 60/70 range. I've not installed any new extensions. Could this possibly have anything to do with Pf? Thank you!
