Hi all,

I am new to Linux - always liked the idea (of UNIX) but now slowly making my move. Was very pleased when I found the BitTorrent clients in Linux, but Azaurus (is that how it is spelled?) was just as slow as it was in Windows and kept crashing on Xubuntu! KTorrent worked like dream and has some nice features (including being very light), but since day one I am not convinced that it is using the 100% (or even 50%) of the bandwidth. My favourite client BitComet (KTorrent is second, so far) used to easily give me 110KB Downloads on a single download, but hardly every get this from KTorrent. I have checked, and checked again, and again and all the ports are open on the Firewall, no problems being logged on the Firewall or anywhere else that I am aware of. I have given it three individual ports (1 x Port, 1 x UDP Tracker Port, 1 x DHT). Set the Max Connection per Torrent to 250, Max Global Connections to 1,000 (however, these are never reached as most of the times there is only 1 torrent in the download queue). Wondering if this is a known issue and something being worked on? I really don’t want to switch from KTorrent to BitComet using Wine, or even when (eventually) they release the Linux version – I like how easy and simple KTorrent is.

So, help please!

Thanks & Keep up the good work.

You didn't mention what version are you using. The latest 2.1 beta1 has many speed improvements so I suggest you try that and see how it goes.

Yes - the version (no matter how much I try I was going to miss something ). It is 2.0.3 on Xubuntu 6.10. Machine is AMD K62 (3D now) 500, 128MB RAM 10/100MB Net.

I will try the Beta version and see how it goes. Will let you know.

Thanks again.

Err... what do I need to install on my machine before I can compile the downloaded update? I have tried the instructions from the site (i.e. ./confgure, make, make install) but get the message

Code: Select all

checking for C compiler default output file name... configure: error: C compiler cannot create executables

I guess I don't have a valid C Compiler installed on the machine - tried going through the package lists and there are loads of languages, problem (as Neo is told) is "choice". Any advice which one I should install from the "Add/Remove..." or "Synaptic Package Manager"?

Thanks in advance for help.[/quote]

Wild guess which doesn't come with any guarantees: kdelibs

Read it all, including this: sudo apt-get build-dep ktorrent

No client should be able to match bitcomet in speed period.

Bitcomet clients have already been banned from numerous trackers due to various different infringements such as:
- reporting incorrect data/share ratios to trackers.
- enabling DHT on private networks (which effectively bypasses the need to register on the tracker)

Some of the other behaviour it used to do/still doing is deny most requests from other clients to upload data. In otherwords the client was designed for leeching ****.

The client has been desigend to cheat, steal and exploit the system for favourable speeds. To combat this a well known bittorrent client actually gives bitcomet a lower priority.

From my own opinion (i have only used 2.1 beta1) the speed is the best i have seen from any bittorrent client, even better than utorrent. To test things i set the max upload speed to 1kb/s and left the download speed unlimited. It was able to download at 51Kb/s on a 512k link (as good as you are going to get downloading via any protocol), this means that either ktorrent or the bittorrent client are very efficient or maybe both , i would have thought under these test circumstances that it wouldn't even be able to send out the requests for new information as the upload data cap would have been reached. I was wrong.

Ktorrent was able to connect to 39peers (i have max40 peers per torrent) and reach 50Kb/sec within 10 seconds of pressing start download. The client is extremely quick in picking up seeds.

I wouldn't be having such excessive max peers or peers per torrent as most modem's actually slowdown to a crawl when there is too many active connections. Try max 100 Connections global, max 100 connections per torrent. Run one torrent and see what speed you get.

I also noticed KTorrent 2.0.3 to be very slow: max speeds I get are 20-30 kB/s in download and 40-50kB/s in upload with a 640kbps ADSL. Azureus downloads at 100-150 kB/s...

I'm not gonna try the 2.1 version until stable... I hope KT' devs are gonna make us a very special Christmas gift!
