"Tweaking" uTorrent is moreso optimizing it instead of going for "what's in the box." That's like going out and buying a dSLR camera and never using the functions to take the pictures you want.
Like I said, go with what I was saying about doing the math and calculating for your connection. You will not download anything faster than what your bandwidth allows, obviously. However, you CAN maximize that connection for your upload and download transfer rates. Remember that the closer you are to reaching the caps for your upload and download for your P2P, the more hampered your Internet browsing will be (obviously).
Upload speed should be independent of download speed. They shouldn't be "clashing" or anything like that... it's a two-lane highway there.
@Anwii: You can set up the number of simultaneous downloads through the options instead of falsifying your connection speed using the Speed Guide. Like I said, though, if you don't provide your own numbers to "tweak" uTorrent, your computer will try to make a set number of connections multiplied by the number of active uploads/downloads, and if you bombard your router with all of these incoming and outgoing requests, your Internet surfing will suffer. That's why I suggest you tone down the number of
connections manually (not active downloads). Also, in that way, by "tweaking," you can actually have good transfer rates without killing your household Internet connection.
I don't know what the real differences are between uTorrent versions... you'd best be off reviewing the revision history. I know that before, uTorrent was downloaded as a stand-alone application. Now, you are presented with installation, although I suspect that it simply just places the application in a standard location to prevent people from accidental moving or deleting the uTorrent application (i.e. into the Program Files\uTorrent folder).
