I am seeing this problem too, even with lastest version (3.2rc1)

i have the kvirc-4.2 and am having problem with the number of seeds/peers ktorrent gets connected...at first it begins alright (50/75) but then after about 10-15 min it falls to 17/75 (so does the speed) and i have to manually announce to the tracker and then it finds again seeds/peers (45/75) and the speed gets up again...with utorrent using wine i don't have such problems...the punctuation from the initial seed/peers(50/75) goes to 35/75 at the worst...this behaviour of ktorrent affects the speed very much...does anyone know why this happen? is there possibly a solution to hinder such a behaviour?

I built and installed KT 3.2 the other day, there is still an issue with letting in the peers.
Here is a fresh image

Notice the amount of peers available vs the amount connected, as you can see it is ~1%

Another fresh one taken today....

This is not a speed issue as other torrents can go lots faster, its a let in more peers dagnamit !!


I think its time to try out Transmission and/or Deluge...

<edit> 8 mins of using Deluge </edit>

Same here, but some more interesting observations:

1. 20Mbps link, professional ISP grade Mikrotik router on it. Connection limit set to 2k for my endpoint on the router for decency sake.

2. Other BT clients (utorrent) work using up to 2k connections without problems. Network diag shows no problems creating 2k test connections with 12-15Mbps traffic (can't go higher due to CPU limits on this particular Mikrotik box). Link should take about 10k connections actually, but the router won't. No bother, 2k connections is goodie goodie anyways.

3. KTorrent having a torrent with >30k peers does exactly what was given here already - connects to less than 1% of peers and that's it... but now the best part:

4. If I start 10 torrents at the same time, each >10k peers, total limits in KTorrent 2k total connections, 200 connections limit per torrent, Queue Manager set to 10 parallel downloads... it connects to 20-30 peers for first 4 torrents and doesn't connect at all to subsequent ones (!). They just hang as "stalled" until one of the torrents being downloaded is finished and only then they start getting a couple of peers.

Seems like some hardcoded connection limit and a very low one at that, but I can't see the exact number, it seems to vary between 100-150 connections in total, regardless of total connection limits, per-torrent limits or link capacity (which is huge anyway in my case).

While I LOVE KTorrent (especially the new file order functionality, yum!), this is rather frustrating when I want a file with 2k seeds, 100 leachers and I'm getting 1Kbps from two peeps for days because it just won't connect to more.

I am happy to help with more testing if needed, I'm a developer myself, so while not very verse with KDE I think I can try and test a bit at least.

So, no criticism, KTorrent is yum yum, it's just that there seems to be a rather annoying bug there.

Version 3.3rc1 shipped with KDE 4.3.3 does not show this behaviour for me, it creates new connections until filling the configuration limits or driving the router into the ground.

SOLVED for me.
