Why does uploading on Bittorrent slow my Comcast internet connection?
Yeah, “KBps” or “KB/s” are also is used to mean kilobytes. “Kbps” on the other hand, is ambiguous; it’s often used for both, so therefore not advisable. It’s the ‘B’ that should be capitalized, since it’s the bit that distinguishes bytes. Oh, well, it’s all so confusing. Anyway, 13 of any of the above is way too slow. You might have better luck moving to Japan.
Comcast advertises, according to your previous message, a 256 kbits/second rate = 32 kbytes/s in theory. If you’re getting 13 kbytes/s from bit torrent then that is about 105 kbits/s. So there are a few questions: * how accurate is bit torrent’s assesment of the upload rate? * what traffic is bit torrent using that is not included in the rate? For example, keeping in contact with the tracker and other clients, acknowledging packets, etc. * What other traffic is going through the network connection at the same time? * Is comcast lying about the upload bandwidth cap? I wouldn’t be surprised in bit torrent is using 50% more than the noted amount when you take into account miscellaneous communication. It’s not a very efficient protocol on the individual user level. I find I can rarely do better than 16 kbytes/s upload even though I also am supposed to have 256 kbits/s = 32 kbytes/s upload rates. On the other hand I *can* easily upload 25 kbytes/s or more with FTP or even scp. It’s not an o
When you max out your upload then downloads suffer as well. In TCP/IP you are always trying to send a packet saying “hey I got your packet, send me another.” If upload is swamped then those “hey” packets are slow to get out, thus slowing everything down. There is a bittorrent client called bittornado which lets you limit upload speeds.
