Deluge is great but a possible problem?

[jojoman02]

I've noticed one thing in deluge, the speed i get on torrents is very variable at first i thought it was a problem with the connection and then i realized other bittorrent clients run great and even deluge runs great with certain torrents. then one day i noticed two torrents that when i started them went fairly fast (above 40Kb/s for me) and when i paused those torrent and started others, they went slow. i waited more than 10 min with both torrents and in the end concluded this by trying multiple torrents with similar properties that torrents with 1000's of peers/seeds (~8k+) has significantly slow download speeds verses torrents with small number of seeds and peers (in the hundreds) this also was NOT due to the seeders/peers ratio's as sometimes the torrents with larger number of users had a better seeder/peers ratio but poor download speed (below 5Kb/s). After all that i believe that deluge might have a problem with torrents with large networks.If everyone could please try this and report on this forum to see if it's just me or deluge so that we can make this great bittorrent client even better.

Deluge doesn't support encrypting, when downloading from other clients which do support it, it will be slower.
Unfortunately the most popular clients do support that. (uTorrent, Azureus)

It even comes to a point where Deluge is ridiculously slow compared to e.g. Azureus.
Deluge is certainly a very promising project, and I will follow its progress, but right now it is no alternative to Azureus, compared in features and in speed.

Anyway keep up the good work :)

you are assuming that a majority of users actually know what encrypting is and have it turned on (it's not on by default in neither azureus or utorrent - correct me if i'm wrong) i believe this to be untrue. either way most users that DO have encryption most likely enabled allow "legacy connections" (as utorrent calls it) in. So that wouldn't affect deluge speeds, unless the users strictly only allows encrypted connections. I don't think that encryption, although an important feature, is causing the slowdown.

not supporting encryption may lower the download speed IF your or the other end's ISP throttles bittorrent connections.

Some ISPs even throttles encrypted connections though.

Truth to this. I wonder what other possibility there is for the lack of speed in Deluge. Must be a bad design then.

Anyways, that's just means much room for improvement :)
