So, i have installed lion for about 3 weeks now. before that, my mac's hardisk died because of some disk i/o error so i had to get a new hardisk, apple employee offered me an upgrade to lion, so i said yea! my mac spec is 2.66 ghz, intel i7, 8gb ram mid 15" macbook pro 2010 model however, when im using lion and using vmware fusion or just running videos on web browser or vlc, my mac tend to get mini freezes every 5 min to an hour, sometime if i am playing games on my vmware, i have experienced freezes that i had to restart my computer to solve cos it just stay frozen. i have tried repairing disk permission but it dosen't help. i have never experienced these freezes/lag before my new hardisk/new os version installed if anyone know how to fix this problem or generally speed up lion help appreciated, thanks!
