Sharing an Equal Network.

Hi. I currently have a problem. My computer is on a home network with about five different computers, and for the most part we could all be using the internet and whatnot and i get no latency problems. The only thing is when my brother decides to download a huge file from bittorrent (which i dont recommend but he does it anyway) my computers latency seems to increase from about 90 to 1000. There seems to be nothing i can really do about it. If i stop his download my connection is better. Is there a way to equal the usage when he does big downloads like this via the network? It would be nice to be able to surf the internet and or play games without lag when he does this.

Perils of P2P File Sharing.

The nature of P2P filesharing is so that even if one is using a "clean" program, many of the files downloaded from non-documented sources have the potential of being infected. More than half of all files available for download from peer-to-peer networks have been deliberately infected with some form of malware.

If you don't see that happening in the foreseeable future..
Your brother should look into changing the settings in his torrent client - specifically Upload and Download speed. Set them at 70-80% of your actual connection speed (which can be tested at http://www.speedtest.net/). It would also improve your latency if he reduces the maximum number of connections his torrent client makes.
