I not really like compare paralleles with FUSION, because think prallels its really better but why FUSION on IDLE use just 7% of system? and paralleles around 40 or 50% specially when have usb conected? My setup is windows xp + one touchscreen USB conected, and cpu on idle its very high, around 40% or 50%. I have configured my mac on dual view, i run window on external LCD with USB connected. Under fusion this not happen with same setup. Some util info to inform for make developer team take a look on this? Unde fusion you can select 1 cpu or 2 cpu, nder paralleles, how is? Paralleles use the 2 cores all time? just use one? Sombody can explainme this? Bets regards.
