I'm worried by the low, low speed of version 1.0.3. I set Deluge to use up ALL available bandwidth, and it is about 4-5 times SLOWER than version 0.5. What can I change? Usually, with my not-so-great ADSL connection, I managed 150 Kib/s; now I'm barely up to 30 -- a huge step backward!
I once even wrote ( http://www.linux.com/feature/123253 ) an article on Deluge, ending with "There are dozens of BitTorrent clients available, but if you're looking for one that both is powerful and has a small footprint, consider Deluge." Now, I wouldn't recommend Deluge to anybody -- it's easily at the bottom of the list in terms of speed! Why is that so? And, more important... what can I do?
Thanks!
Slow speed with no download limits
Re: Slow speed with no download limits
Don't max out all your connections - this will cause slows downloads.
Did you do a fresh install of 1.0.3 or was it an upgrade? 1.0.3 should have had sane default values (as opposed to unlimited).
Use the settings indicated here: http://dev.deluge-torrent.org/wiki/Faq# ... shouldIuse as a starting point.
You should also have a read of this which explains why you may notice a speed difference between 0.5 and 1.0.

Re: Slow speed with no download limits
Sorry, but I'm not buying this. I deleted all the configuration files after getting such bad results, installed Deluge again, and got the default parameters suggested at the link. I set the maximum connections to 100 (and then even to 50), and the upload speed to 3 maximum, and total speed is still about one fourth or one fifth of what it used to be.
I don't believe either that this is a matter of taking overhead into account -- the fact is that it took about 8 hours to download something that used to take just a bit over an hour. And, I did several experiments, on different days, and it was always the same. (Unhappily, the graph plugin isn't there, though the site says all plugins are included with the client... what gives?)
So, I'm guessing the real problem is that somebody goofed up quite seriously when doing the big code changes from version 0.5 to 1.0, and that isn't being accepted... Face it, Deluge went from being the top program in terms of speed, to being the worst of the pile! Since I started having so many problems with Deluge, I went back to old alternatives like KTorrent, which now shines in comparison (!!!).
Please, do give this problem a look, and stop blaming the "protocol overhead" -- that cannot be causing such a slowdown.

Re: Slow speed with no download limits
As a further test, I tried setting both the download and upload limits to "maximum", and I could only get the download speed up to 50 kibs -- one third of what I used to get.

Saturating your upstream will give you poor download speeds.fkereki wrote:As a further test, I tried setting both the download and upload limits to "maximum", and I could only get the download speed up to 50 kibs -- one third of what I used to get.
Re: Slow speed with no download limits
I had this problem also. I deleted all conf files and all torrents and for now it seems to be working better.
But still, i don't think if you are seeding like 20 torrents your download speed should go down like that (it doesn't happen in uTorrent, torrentflux...) - btw i did set the upload speed limit, didn't help.

Re: Slow speed with no download limits
I did delete all configuration files (see above) and I worked with just ONE or TWO downloads at the same time. I tried both maximizing and minimizing the upload top speed, while keeping the download top speed at the maximum.
The best download speed I could get was about a third of what I used to get with version 0.5 -- and I'm measuring it by the download time, and not by whatever it says on screen: downloads that were finished in an hour, now take at least three hours to finish.

Re: Slow speed with no download limits
Perhaps your upstream limit is too restricted and it's causing your download speed to suffer.. You should be allocating at least 5% of your expected download speed for your upload limit.fkereki wrote:I did delete all configuration files (see above) and I worked with just ONE or TWO downloads at the same time.

Re: Slow speed with no download limits
When I set the upload speed to maximum, it was 10% of the download speed (my ADSL is really quite Asymmetric!) and results were as bad as in other cases.andar wrote:Perhaps your upstream limit is too restricted and it's causing your download speed to suffer..

What bothers me the most is that Deluge 0.5 worked excellently well, and I cannot get even close to it with Deluge 1.0....
Re: Slow speed with no download limits
Unfortunately I am having the same problems. Not to offend, but I doubt that "overheads" are going to cause me speed differences like 750KB/s on Transmission to 40KB/s on Deluge with the same set of torrents. Not a scientific test mind you, but things should be closer than that. I deleted my entire Deluge configuration in hopes that would fix it too.
I too have great respect for this client and would normally move on without any sort of feedback. There is something wrong for an (apparently) small group of people using this client. There must be something common with this group, though I couldn't say what it is.
