Hi George,

I experienced a very low down speed for one particular torrent, and looking at peer list I noticed too many "snubbed". Yesterday I downloaded latest KTorrent from SVN, but the problem persisted there also. I grep'ed sources and did following, and now that torrent is much faster.

Just for your info.

Interesting, I will have to experiment a bit with this value.

Are you sure this is not just one big seeder which came along at the right time ?

It's possible. But I definitely see something is wrong with downloading algorithm. Usually looking at peers I see they have 4-6 more percents completed then I have. This is very strange, I did not have such behaviour with qtorrent. My idea was that because of timeouts some peers are getting "snubbed" attribute while they could still be useful.

As a thought: qtorrent worked just perfect downloading files, the problem with it that it is not feature-rich.

If you could document how this thing works in your program and what standard document describes how it should work, I could spend my time thinking with you how to improve things

Snubbed means that the peer hasn't sent you a piece in X amount of time (where X is the value you changed). This has it's influence on choking and uploading

The code is based on http://wiki.theory.org/BitTorrentSpecification, choking algorithm is based upon some paper I found somewhere. Improvements are allways welcome.
