I have installed it and it's extremely quick. It would have to be twice as fast to load pages as firefox.
Give it a try.
chakkaradeep: Me too used for some time and switched back to Firefox Beta (Currently Beta 5). I found webpages to load fast in Safari, but not much plugins/addins and also some sites didnt open properly. FF Beta 5 is worth having it and I find it really fast and less memory usage consumption than FF 2.0!
