I have a 12MB down/1MB upload network connection through my work (I work at an ISP). With torrents, and other misc. uploads, once I get to about 100kb/s upload speed, games and browsing start to come to a crawl. I've uploaded about 400kb/s consistently before so there shouldn't be a cap on it, but why is it that when I get to about 80-100kb/s upload, games and browsing start to lag? I know I have more bandwidth capacity than that?

Are you encrypting your outgoing traffic in your BitTorrent client? Your ISP may be throttling you.

Is it Bits per second (mBps) or Bytes (MB\s)..

Because if you have 12\1 Mb\s connection, then you should be perfectly fine upping at 10%. If you have 1mBps upload, you're near your max, and it is normal to lag then.

Try setting transport encryption to enabled (but not forced).

And could you do a speedtest.net run, without any torrents running? I'm curious to see what you get.

pst... your capolization is wrong XD...

ISP speeds are ALWAYS bits (little b) per second.

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 1\1 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 bit\byte you upload or download has to be processed and written to\read 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.
