Slow speed on transmission

[trider]

Hi

I'm having a bit of trouble with my transmission speed.

I se lots of peers, My firewall is ok.

Any ideas?

Hello

I am having the same problem and it is not the firewall because I have everything working properly prior to this latest Transmissiond upgrade, my setup worked great with speeds over 200KB/s.

With this newest Transmissiond it limits the number of peers to 50, my connections are dog slow with torrents that have over 50 peers connected to me I barely reach 5-10KB/s so my completion times end up taking days instead of hours.

Could someone please tell me how to properly downgrade to 0.8x series. I've tried it myself but I'm getting some error after I run torrents it appears to append word "success" during communication between the daemon and the cgi, or something like that and so no torrent works.

Thanks.

P.S. Oh forgot to add, it's also now constantly checking files. This is very irritating because it is un-necessary to do so until the torrent is complete, yet I see it checking files randomly at any level of completion.

You can imagine when you have couple of torrents, each with 3-4GB of files and it's taking hours to check each of them.

All this had worked fine in the previous Transmissiond...

[mancub]

To follow up on this issue, I have tried downgrading the firmware just to see what happens and there was no change. So this has to be a problem with transmissiond or one of its libraries.

I have 50 peers (maxed out) connected on each torrent and yet I'm only downloading from 5-10 if I'm lucky, which is totally silly.

This might be a long shot, but perhaps some packet encryption is forced/defaulted on with this latest transmissiond (or libraries) and so I'm only downloading from peers that support it, while all the others are sitting there useless because they do not support/need it (I don't need it either, my ISP does not filter torrent traffic).

Any thoughts on the above?

[oleo]

There is no easy way to downgrade as feeds now contain only latest version. I will see if upgrade to latest SVN will help somehow. Otherwise I will prepare some older version 0.82 or other based on your suggestion. It would be helpful if you state from which version to which you've noticed the problems. Then you could file for a ticket directly at http://transmission.m0k.org/trac/

[mancub]

Hi oleo,

Thanks for your reply.

I have always kept my Transmission up to date, so it must have been the latest two versions that changed something, the 0.96 and 0.94.

It's hard for me to remember which one I had prior to those. It could've been 0.91 or 0.84 and I know the speeds were good.

As an alternative, I have installed rtorrent and these problems are not present there. I'm getting over 100KB/s on some of my torrents which makes me happy not having to wait weeks to complete them

[oleo]

Please try transmission_0.96+4300 from chengeset #7486. From my testing it solves mentioned problems with speed lag and possible rechecks.

[mancub]

Hi oleo,

I will try the new build and report here on the results.

Thanks.

[jrosado]

Any success? I also have the same speed problems, but only when I'm download 2GB or bigger torrents files. If i stop downloading this big files, the other torrents get very good speeds..

Something strange is happening here

[mancub]

From limited testing I've done the problem still seems to be there, just even more stranger now.

If I have less than 50 peers connected then I downloading works somewhat, but if the number of peers is maxed out at 50 then it's not downloading from any at all.

What about system load? System may be stressed just by moving disk heads and this results in slow speed.

Please describe your problems at transmission TRAC if you are shure that this is libtransmission problem.

Well..that's one of my suspects, as i said here

But my knowledge is not that big in order i can say: this is sure the problem

My system load has not changed, actually I noticed that it's lower because I have been running rtorrent instead of transmission past few days. So when I did the test I had five torrents in rtorrent and two in transmission and my load was around 1.5, if I recall correctly...

[jrosado]

Well..I'm having the same problems with transmission: slow speed and high cpu usage. Were can i get the .8xx version for the wl500gP ? I want to go back (i rather live with a 2GB limited version than a version that simply does not push any torrent )

[oleo]

Well? It not so simple any more since we are lacking disk space on build machine. I could build one just for you and put it on my website. Do you use oleg firmware? I am using kamikaze and not having much troubles with transmission. See my recent transfer graph.
