Hang fire a second ... that TF article is showing bandwidth used as a % ... a percentage of what exactly?

Yes it might be a bigger slice of the bandwidth pie, so to speak, but if the upstream pie is smaller (due to lower last mile bitrate) then surely upload traffic on an absolute scale when compared to download would be lower?

Don't BT clients stop seeding once you hit a 1:1 ratio anyway? Vuze defaults to 0.5:1.

Without traffic shaping in place, P2P traffic will always consume more upstream bandwidth than down, demonstrated by the TF article.

Although it can consume more that is not always the case, as unless there are lots of peers connected to you at the same time, then it isn't going to saturate the connection, or even use all available resources, It's just BT and their backward thinking and the fact that they don't like customers actually using their connections ,or using their connections for P2P they never have or will do

Upload speed is equally important to quiet a few non commercial users , and to cap /throttle it to a poxy 1mb or less ,is just wrong,

They shouldn't do. Vuze is considered a trashy client in the torrent scene. uTorrent & rTorrent don't have limits in-place unless configured by the user.

Sharing is caring and all that.

Yes, I'm sure they just throttle P2P upstream for the sake of it.

Bad logic -- you're assuming that infinite amounts of people want to download that torrent and few other seeds. In reality, the torrent soon gets saturated and the other seeders compete to upload.

Not an issue if it's a public torrent. It's advisable to seed multiple torrents at private trackers.

Without traffic shaping in place, P2P traffic will always consume more upstream bandwidth than down, demonstrated by the TF article. As Brammers pointed out below, that is as a proportion, not an absolute. It's a proportion of the smaller pot of all upload traffic. On average, we can be sure that P2P will consume the exactly the same upload as download bandwidth. Every byte that anyone downloads has been uploaded by exactly one other person, so the total upload equals the total download.

Of course, total upload == total download applies everywhere else except broadcast applications. It is just that for most protocols the uploaders are largely servers and not peers ~ they would count in a survey of all internet usage, but not of all broadband usage.

I am talking about total bandwidth tho, isp's have more customers than just heavy torrent uploaders. They dont buy bandwidth just for torrents. Also some torrent users may not even upload at all, private torrent sites eg. sell upload stats for cash so the people who pay dont have to upload to maintain a ratio. Some others buy seed boxes and this stops them uploading on broadband as well. Some just leech regardless. So yes whilst some may upload heavily its by no means everyone. Not to mention someone could just be a very casual torrent user and be affected by this draconian throttle.

I am not saying I am right, I am not sure, but it would be nice to see something solid that indicates unthrottled torrent usage can saturate an isp, sky seem to manage not managing it. VM's capacity is very async much more so than the 2:1 quoted for those new msan's so they not a very good test case.

The reasoning is that plenty of torrent applications do not stop seeding. Many like frostwire vuze etc will seed forever. They run at startup too, so whenever the machine is on the user is uploading. This uses far more than the original download and over a week, month, year etc

Also if users have lots of torrents uploading all at once it can saturate the uplink. This is difficult with FIbre but was certainly a bigger issue on ADSL. This in turn can slow down the overall download speeds.

This being said, the throttling seems pointless as the Fibre connection should easily handle the uploading anyway.

BT for you. I have infinity and Sky Fibre. Definitely see the upload restricted, sometimes as low as 1.5 Kb/s (for a few minutes) and then it will jump to around 70 / 80 Kbps. It's 24/7 and is quite frankly annoying.
