That's correct. No slowdown through subsystem emulation and loading x86 dlls. Native 64bit processing is faster also. There are enough benchmarks out there. One more advantage is the windows memory limitations. There is an limit which all 32bit applications can use together on an 64bit windows system even if you have 1TB of ram. If you run 100's of 32bit processes at the same time they can't use it. So depending on how much your utorrent did consume this memory is „free" for other 32bit processes like games for example wich nearly all are still 32bit. :cool:
