    Hey guys,
    After I got ML I did a fresh install. and ever since it has been way slower than on lion. Like when opening from sleep. Did the fresh install mess-up?

    should i do another?

    Try reinstalling ML, my rMBP is speedier than ever since I installed ML. Waking my machine from sleep is about 2 seconds before everything resumes. If it is along this range than it is perfectly normal, although maybe you have several intensive apps opened that are conflicting with your slow wake up times?

    Regarding wakening from sleep, see this thread:

    I am also finding my rMBP faster with ML, might want to try a clean install if thats an option.
