My MP is a 2008 8 Core (3.2Ghz) w/ 16GB of RAM, so it's fairly decent in speed, albeit older. So I had upgraded to Lion a few months ago (when it came out) and it is very very slow. I had Snow Leopard before this. Mission control, Adobe Applications are slow and disrupt my workflow. Should I just reinstall SL? I don't see Apple fixing the slowdowns as Lion is on 10.7.3 now.
