Windows XP is said to have a connection limit. There are some patches that increase this limit to 100 or higher. I was just wondering if my download speed (from torrents, etc.) or number of simultaneous downloads depend on it?
This connection limit, limits the amount of connections your computer can have, so, if you get lucky and find a peer with very high upload speed, you will not be affected - but - in most situations, it will affect torrent speed.
If you do a lot of torrenting, I recommend you apply the patch.
For everyday non peer to peer work, it is unlikely you will benefit from this patch.
