delimare Posted December 7, 2006 Report Share Posted December 7, 2006 Here is the scenario: I have a max download around 2MB/s. I will be downloading say 30 or so torrents from a specific site getting a steady speed of 750KB/s. Once the torrents start to finish and I'm down to only 10 or less my download speed kicks up to about 1 or 1.2 MB/s. If I'm down to 3 or less torrents and I'm leeching off peers who have amazing uploads I'll get around 1.5 to 1.8MB/s download. I understand that the more torrents I have the more peers I'm connected to and the more information is being passed, but is that really enough to bog down my connection that much? Maybe it is, maybe not. I am not at all concerned about maxing out my connection and this isn't about being a speed junkie. This is just a pattern I've noticed and I was curious if anyone had an answer. Thanks! Link to comment Share on other sites More sharing options...
Lucky75 Posted December 12, 2006 Report Share Posted December 12, 2006 Really? The more you download the slower each download gets? I wonder why that is...? Link to comment Share on other sites More sharing options...
delimare Posted December 12, 2006 Author Report Share Posted December 12, 2006 I'm sorry, I should have made it a bit more clear for you. I'm referring to overall speed, not speed per torrent. Link to comment Share on other sites More sharing options...
Lucky75 Posted December 12, 2006 Report Share Posted December 12, 2006 what router? Link to comment Share on other sites More sharing options...
delimare Posted December 12, 2006 Author Report Share Posted December 12, 2006 I have tried two. An older d-link (I forget the model) and the new Rangemax Next Netgear with the N technology. BUT... I also see the same results when direct to the modem. I have a second modem too that I've tried. While it doesn't have the speed of my main modem it does have a cap of 1 MB/s. This one also will never go above 750KB/s. Something interesting I'd like to note. When I initially start uTorrent or if I resume from an all torrents paused status, the speed will skyrocket to the full 2MB/s speed for 45-60 seconds before plummeting back down to the 750-1500KB/s range. This will happen on my 2nd modem as well. It will cap out at 1MB/s before lowering down to the 750/KB/s. I've juggled with the thought that my ISP (Comcast) shapes P2P but then why would it vary from 750 all the way up to 1500KB/s? Like I mentioned, the only thing that seems to affect speed is the number of torrents I run. Link to comment Share on other sites More sharing options...
Switeck Posted December 12, 2006 Report Share Posted December 12, 2006 You need to look at the UPLOAD side if you want to understand why this is.So firstly, what's your connection's SUSTAINABLE upload rate?Being that BitTorrent is loosely based on tit-for-tat, if you're uploading slower to people they'll likely be uploading less back to you...and uploading more to someone else who is more giving.So it would make sense that if your average upload speed PER total upload slots falls below 3 KB/sec, that speeds might suffer...and if that value falls below 1 KB/sec speed WILL suffer. Below 0.2 KB/sec, results can be really 1-sided...you might be uploading at 100 KB/sec and getting less than 10 KB/sec back! Link to comment Share on other sites More sharing options...
delimare Posted December 12, 2006 Author Report Share Posted December 12, 2006 I have a top upload of 300KB/s that I usually dumb down to 50-80% while downloading. I understand what you're saying though... thanks for the reply. Link to comment Share on other sites More sharing options...
