I am happy with Snow Leopard performance, particularly start up times (from switching on to being ready to run an application) are significantly improved. So sorry, Sumdumguy, it's not a general problem. I can't think what else to suggest as you have tried the obvious repairing permissions and reinstall. Are you perhaps running some application in the background that is not Snow Leopard compatible and could be causing these slow downs? MacInTouch have a Snow Leopard compatability list that may help.
