Very slow upload speed under Windows 7

[mcoquet]

Hello

The question may have been asked already but let me be specific about it. I am using :

* uTorrent 1.8.5 (build 17414), since version 2 is not compatible with some trackers I use

* Windows 7 (64 bits edition)

* My ISP is "Free" (French ISP), which is very reliable and on which I have performed speed tests which gave positive results (i.e. in accordance with my theoretical DL/UL speeds)

* The green tickmarck appears and ports are forwarded properly through a router with UPnP

Problem is, while my DL speed is always optimal (ca. 1.3 Mb/s), my UL speed is always crappy (i.e. 3 to 5 kB/s when it should be around 100 kB/s). What could go wrong here ?

I tested this with a large variety of trackers and I always get the same results, except for piratebay for some reason ?

Thanks in advance to whomever could help me solve this annoying issue....

ADSL?

Overseeded torrents?

ISP throttling?

The piratebay supposedly no longer runs trackers.

Thanks Switeck

I am using ADSL over Wi-Fi with a router, in a configuration that actually worked perfectly well while under Win Vista 32 bits

My ISP doesn't seem to be throttling torrents (at least according to Glasnost tests)

As for overseeding, how would I be able to assess this please ?

[Switeck]

For instance...if the torrents report 100 seeds but only 10 peers, it's very overseeded.

The few peers you see are likely the (very) slow ones that failed to download quickly from the many seeds that could and probably did connect to it.

thanks for the quick reply. I'll run additional tests over time and see how it goes then...

Run 2.0.2 and use better trackers that do allow it.
