Hi, I have a 190+ user environment with 2 T1 circuits going out to the internet. My users sometime complain that their internet connections are slow. All of them are running on IE6 at the present time. I'm planning to upgrade everyone to IE8 and I am considering things like accelerators, smartscreen filter, etc. Does anyone know what kind of a performance degredation I can experience from enabling some of these features that were not available in IE6?
