 Slow Torrents With Windows XP sp2

 Windows xp sp2 limits your TCP connection to a maximum of 10 which really boggs down your torrent speeds. Here is some information from a guide I located that explains how to get rid of that TCP connection limit and speed those torrents back up.

Excerpt from "Speed up your torrents"

Hack the max TCP connections

If you’re on XP sp2, your TCP connections are limited to a maximum of 10. This seriously hurts your downloading speed because it wont let you connect to a high amount of ip numbers. It is supposed to slow down viruses because their spreading strategy is to connect to a high amount of ip numbers, but it also cripples your torrent downloads.
A nice way to fix this is to download this patch, it allows you to set the maximum allowed connections to any number you want. Any number between 50 and 100 is ok (more on this).
