Strange behavior at download with 17341 build utorrent 2.0 beta

[sanyigz]

I started to download a torrent from a a multinational tracker, and it had 3 seeds, and the download was at 4-30 kbyte/sec for days. Now i started to download something from a tracker where the most of users are from my country. I have 1,8 mbyte/sec downstream bandwidht, and as always the download speed from the second tracker risen rapidly, and same time the first tracker's torrent download speed raised too! When the second torrent finished, the first torrents download speed fallen to 14kbyte/sec again. Then i started do download another new torrent, and as the third torrend dl speed rised, in same time the first torrent speed risen too to ~500 kbyte/sec.

It's not a dl speed indicator bug, cuz it's really downloading faster.

Maybe a bug with utorrent's internal bandwidth regulator?

That could be a problem with very slow/poor uTP peers/seeds causing uTorrent to vastly underestimate available max download...and probably max upload as well!

1st link in my signature (slow speed section) should help.

My isb don't manipulate the torrent traffic, so its not problem. I tried the bt.transp_disposition setting, i will see how it works.

But another problem: i use upnp router, and utorrent sometimes spamming the router with requests with very fast repeating sometimes 6 times in a second:

[2009-11-26 14:46:28] DEBUG: UPnP: Got a reply/notify event

[2009-11-26 14:46:28] UPnP: Found location from upnp notify: http://192.168.0.1:80/igdnew.xml

this is happening after all port mappings finished and working, and utorrent got the external ip too.

Your ISP may not, but you may be connecting to peers/seeds on bad ISPs.

A slow uTP can also be caused by bad settings or bad networking on their end.

If you did manual port forwarding on your router, you should be able to disable UPnP in uTorrent.
