hi, i recently bought a 2010 mbp and got the feeling that it performs relatively bad. i'm running chrome (blib.tv video loading, same problem with firefox), adium, things and the sc2 beta in the background. memory (4gb) is used up to half, fans running at 6000rpm, cpu idle 48% and its quiete laggy overall. i would understand the laggyness if the memory would be used completely and cpu would runnning at 100%, but thats not the case. it seems like the mbp is underperforming, is there an easy way to test the performance? i know the sc2 beta performance is quiete bad, but is this really slowing down the whole mb? thanks for your answers.
