Hi, I have an internet connection that is supposed to be 20mbit/s and I was wondering how fast is that supposed to download? The fastest speed that I get is 1.8mb/s in uTorrent. I know that mbit/s and mb/s are not the same, so I'm wondering if there is an actual conversion between both, to make sure that Videotron is giving me the actual speed that's I'm paying for. Here's my plan : Videotron official Site

to find your actual speed in megabytes, divide your speed by 8
Keep in mind that since torrents relies on 100+ connections for full speed, there is a lot of bandwidth overhead so if you use another tool to monitor your speed, you may see a transfer rate of 2.5MB/s but the torrent client may report just 2.1MB/s (hopefuly you went into your torrent clients options and upped the global max connections to 1000, then upped the per torrent connections to around 200-250)
also run a speedtest.net test to see if you are actually getting the speeds you are paying for.
also be sure to make sure that the torrent client does not use more than half of your benchmarked upload speed. (Since torrents make many connections, each of those connections require their own set of maintenance packets (which are a 2 way process) if your upload becomes saturated, those maintenance pack will be delayed and the seeders will see that as a unstable TCP connection and thus lower the rate until it becomes stable.

larrivee013 when your using torrents your basically getting hw many people can seed to send and receive that file on utorrent the amount of connections for that particular file will cary and the speed will fluxuate as well on that connection. if you go to videotrons web site to test the actual connection speed here http://testvitesse.videotron.ca/index-en.html I am also on the same network of Videotron and I am satisfied with the 8 down and one 1 for me over here. When your running the test from videotron you'll see your connection speed is true enough on their network.

"I know that mbit/s and mb/s are not the same..." Yes, they are the same, speed should never be measured in bytes per second, and is a personal pet peve of mine...
When you get 20 mb/s internet, the 20mb/s means the max speed between you and your ISP, it DOES NOT mean the speed you will be able to connect to another computer for. Packets can take different routs, and can take a different amount of time to get there. In the case of bit torrenting your speed is limited to the upload speed of everyone you are connected to, which in my case is 4 mb/s total. that gets divided by (as of now) 11 machines accessing the internet. it also gets divided by the number of things i'm uploading. Greated you are connected to a bunch of people but you are only getting kb/s from each person.
I have never, nor should anyone ever expect to get all 20 megs from one source.
Fun Fact: the term "byte" has never been officially defined as being 8 bits, but rather like words the meaning has changed... There was a time when a "byte" meant 6 bits, or 10, and even today can mean the same as 9 bits. However, now it is pretty commonly accepted as being just 8 bits.
Same thing with a word, which has 2 meanings now and we commonly use the term word as 16 bits and machine word to mean the address space (up to 64 bits on home computers) but it is not incorrect to use the term word to mean a machine word.
Like the word "gay" which used to mean happy, and later homosexual, and now, in some contexts, can even be used as "stupid." The meaning has changed
