First of all i would like to congratulate you for this great job.I used previous releases of ktorrent and had lots of problems.Since ver2 i have no problems and everything works fine for me.Great job.
Two questions now:
1:How does memory usage(low,medium...) affect ktorrent"s perfomance?
When we say low or high how much memory usage does this mean?
I have 1G of ram.Could i use this option to medium or high?
2:What is DHT and why should i use it?

1: I've heared George saying this is a setting for how many pieces KTorrent should keep cached in ram.
2: DHT is short for Distrubuted Hash Tables. It's just another medium for getting sources on a torrent.

Memory usage is like this :

low : 10 MB of chunks are kept in ram per torrent
medium : 20 MB
high : 40 MB

For most people high usage should not be a problem, it's actually best if you set it to this when you download torrents with big chunk sizes (1 MB, 2 MB ...).

Hum, whould it be possible to set by hand the size of chunk in memory ?
(I have 1GB ddr used half, and when I have around 25-50 torrent in seed it whould save a bit harddrive access...)

40 MB per torrent is more then enough, you can only download so many chunks at the same time. (This doesn't apply to stuff in memory for uploading)

Ah, ok, I didn't though that...

I whould be happy to have such feature, but linux kernel take care of caching the needed part, but it may be great to see if some improve can be made in seeding process...
(I know, so many features request, so few time to add them...)
