Here's my opinion. I had disabled some services through BUM which is easier method. With this thread I stopped few more services and the result was that I didn't have no sound (hotkey is needed for that, using regular computer). After fixing sound everything worked but the speed difference was so minimal with modern computer that the whole thing was quite a useless. I don't actually feel any difference with or wothout using the bum to disable services. Using athlon 2800+ and 1 gig of memory with sata hd.
