I am running 10.7.3 on a Macbook 2010 with 2.4ghz C2D, 4GB DDR3 and 250Gb HDD. Lion is running pretty slow, I just opened up iTunes and it took 2 minutes before I could play a song. This is straight after I finished playing Garry's mod - will this matter? I have no idea why it would be slow I only have about 60GB of the HDD filled up. I was thinking of reinstalling it (clean install is out of the question), will this make much of a difference? I have used recovery to verify and fix permissions etc. Any ideas would be a great help!
