Issue with certain torrent speeds


Recommended Posts

Original post:


Having probs with speeds of certain torrents. I'm using uTorrent 1.8 on PC running Vista with unpatched tcpip.sys file, my connection is Sky ADSL (d/l usually around 850kB, upload about 70-80kB).

Recently went from d/l'ing at full speed to 11.5kB per torrent... I thought I'd check this and when using OpenOffice and Linux torrents I get 300+kB so I think it must be my ISP throttling certain trackers.

Is there a way to get round this?

Oops :rolleyes:

Looks like I found the culprit, my global u/l rate was set to 6Kb instead of 60 - when changed normal service was resumed.

Anyone please tell me why that happens with certain torrents and not say Linux ones?

That's an unfortunate side-effect of the peculiarities of TCP/IP networking. Capping upload speed limits not only how fast you're uploading but also how fast you can send out requests for seeds and peers to KEEP uploading to you. They don't get those requests, they assume they or you are overloaded...and slow down.

The Linux torrents don't require you to upload at all...so even when upload speed is set really low, they still download quickly. Even when you're already overloaded on the upload side, the seeds are so fast and numerous they still often manage to slam as much down to you as your connection allows.
