This is quite a simple explination. Even though your connection speed can handle 400kbps, this doesn't mean "you have 300 more to spare". Your NIC can still only fire off 1 packet of information at a time. If you're uploading at 50kbps then (all numbers past this point are for reference only, not real numbers) your NIC may fire 1 torrent packet, 1 game packet, and alternte as such. The more traffic you're generating to the torrent (such as 100kbps or higher) the more spread out your gaming packets are going to become. So now as opposed to a 11 ration, you're now firing 3 torrent packets and then 1 gaming packet. This increases your ping, and as such relaying game information, or HTTP requests takes longer. Also the faster you're uploading, the more your HDD is being used as well as your processor since every bitbyte you upload or download has to be processed and written toread from the HDD.
Then why, when I'm using torrents, I can upload at 90% of my max speed (100\\112.5), and experince almost no lag on the internet. I forgot I had torrents going one time, and my gaming experince was completly uneffected.
I highly doubt having the harddrive being busy would be any part of it. Newer drives can write upwards of 60 MB\\s, and that's around 500mbps. And most torrent programs use 1-3% of CPU usage, if that.
The NIC upload thing makes sense though, when I unlimit my upload speed (applying powerboost to it, raising the cap to ~280 kb\\s) my connection drops noticably.
