flak Posted March 3, 2006 Report Share Posted March 3, 2006 I've been using utorrent with great success for a while now and when the odd issue cropped up, I've usually been able to find a solution by searching these forums. So let me first say a big thank you to everybody for such a great resource.Now onto my problem:For the last week, my download speeds have dipped dramatically - up to 80%. I suspect the upload speed is impacting on this because though I am connected to the same average seeds and peers as before, the upload speed during downloading peaks between 5 - 10 Kb/s, well short of the 47Kb/s I've set in utorrent. This happens for all torrents I've tried. Interestingly, once downloading is complete and I am just seeding, the figures increase somewhat, but still not to the levels I had before. FYI, I am listed as connectable at the private BT sites I use.I've used the utorrent network wizard to assign the settings for me, so I doubt the problem lies there. As a test, I disabled all firewalls, connected my DSL directly to my PC ethernet network card (no router); still no joy. I even uninstalled cfosspeed just in case it was dong something wierd (worked like a dream before) just to see if that was affecting things, but no. I've tried rebooting and FWIW, the first torrent I download reaches acceptable download speeds even if well short than before. Once I download a second or third torrent, however, the speeds drop steeply. I used TCP optimizer to tweak latency, MTU etc. I tried the latest utorrent beta build, no dice. As a last resort, I contacted my ISP who were helpful enough but couldn't explain what was happening because when downloading non-BT stuff and using the web browser, I get exactly the speeds I'm supposed to. They assure me that no traffic-shaping is beiing performed from their end.If I were to guess, my upload speed is being somehow throttled and that in turn is impacting on the download speed (or vice-versa). I can connect to as many peers as before but its as if something is actively refusing to upload to to each indvidual peer beyond fractions of a kB.Using:Realtek RTL8139/810x Family Fast Ethernet NICutorrent 1.4TCP patched to 100 half-open connectionsDSL broadband 6M line (640kB/s down; 64kB/s up)Global max. upload rate = 47kB/sGlobal max. download = unlimitedGlobal max. connections = 250Connected peers per torrent = 90Upload slots per torrent = 4Additional upload slots if <90% = checkedAssuming similar number of seeds/peers, typical speeds BEFORE: 300kB/s down; 46kB/s upSeeding only = 60kB/s and upwardsNOW:50kB/s down; 6kB/s upSeeding only = 15kB/sAny suggestions?
