How do you make utorrent 1.8.3 faster?

These are the basic principles of optimizing a bittorrent client, like µTorrent, for speed: * Choose a proper port to avoid ISP blocks and conflicts with other programs * Forward that port through any software firewall and router to allow incoming connections * Adjust internal settings based upon upload capacity of the internet connection to allow room for outgoing communications and to distribute upload efficiently.

There are guides on the internet to help with forwarding the port through the firewall and router.

The guide in the related link has links to those as well as screen shots of µTorrent and information to help with adjusting internal settings and choosing a proper port.
