[trider]

Hi

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 :D

[oleo]

Please try transmission_0.96+4300 from chengeset #7486 (http://trac.nslu2-linux.org/optware/changeset/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 :confused:

[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. :confused:

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 (http://transmission.m0k.org/trac/) if you are shure that this is libtransmission problem.

Well..that's one of my suspects, as i said here (http://wl500g.info/showthread.php?t=6823&page=15)

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

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 :mad:)

[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.

I use oleg firmware. I think the problem is on the high cpu usage that big torrent files make. At the moment, I'm downloading a 40GB torrent (about 180 files of 350MB and 700MB) and the cpu usage is very high (allways above 2.0). In this torrent, all the files have not been yet created!

Before this i tryed a single 700MB torrent file, and got speeds of 450KB/s :eek:

So, i will wait to see if the asus can manage this other torrent (is almost on it 24 hours, and not all of the 180 files have been created!)

[olfa]

Oh man, this whole transmission experience is lately pure masochistic. Previous build was finally pretty good for me. I was getting whole day constant 40 KB dl speed on public torrent with only 4 seeds and on private torrents my line was maxed 60 seconds after start. As I can't resist to newest builds always hoping for better (don't we all?) I tried today's build. It took me 45 seconds to upgrade and restart transmission. Guess what, I was getting much lower speeds on the same torrent (tried several restarts). Well, one can attribute this to the torrent nature (what is confirmed because while I am writing this post speed goes steadily up).

So I vote that previous build is very good and for the latest build time will tell.:) I think that transmission is back on track.:D

[oleo]

I think that transmission is back on track.:D
I am also sharing your opinion. Latest build 0.96+ (4366) maxes my line as never before.

For huge torrents I cannot tell. I suggest that you install procps package or atop and use top for displaying system load. You will see that normally CPU is 30% idle at system load over 1.0. This means that CPU is not the bottleneck. It is rather i/o.

It helps somehow if you increase cache by upgrading memory. But this is hardware mod. Oleg for example increased its wl500gP to 128MB. I've upgraded two mine wl500gx to 64MB with just 20€ investment.

[jrosado]

Here is my top result:

http://img252.imageshack.us/img252/8357/topcpuyn2.th.jpg (http://img252.imageshack.us/my.php?image=topcpuyn2.jpg)

I do think that the problem is the cpu usage on i/o on the usb hard disk.

Of course if i put transmission with simple torrents, i get great speeds, only limited by the USB speed to the external hard disk.

I don't know if upgrading the memory is worth the risk.

One thing i know is that maybe if i used a NAS disk connected to one of the ethernet ports, the system use could be lower.

I did post a question on this forum about bulding such a system (here (http://wl500g.info/showthread.php?t=11566)), but no one answer :(

[oleo]

It is better to go for NAS that has provision for Transmission than using external NAS for IO. I could not tell you if this approach could help you. Look for router with directly attached disk. Like FSG-3 or WL700gE. Visit www.nslu2-linux.org for more details.

I see from your top that your transmission uses 44MB of memory. 20MB resident. 12MB shared. So you are swapping all the way. There is nothing you could do to increase speed. Except somehow lowering memory usage. Maybe rtorrent is better on that although transmission always claimed its lightweight. atop could tell you if memory consumption has gradient and possible leaking.

Kill rcamd, waveserver and other unused modules to squeeze more memory.

[mancub]

Yes, this latest Transmission build has far better speeds than the previous ones so I think if nothing else surfaces we should stick with it. :)

[oleo]

I would also like to see that Transmission has a stable development, but recent code changes were extreme, from my point of view. I've backed at 0.82 for long time, tried 0.9x for several times and did not want to upgrade until it stabilizes. But meanwhile some users wanted newer releases. I've resisted for some time. Then bzhou upgraded Transmission and broke things. I've corrected things. Optware lost its ability of older versions and so on. So the saga continues. It looks like there will be Transmission 1.0 in near future. Anyway, I will not upgrade Transmission untill 5th Jan. 2008 as my 500GB disk failed to go through fsck and the whole computer is inaccessible to me until then :)

[mancub]

Hmm, there still might be something wrong with this latest Transmission.

I am at 50 peers (max) on two torrents, yet only downloading from 5-10. That's rather wasteful especially if there are over 200 peers on both torrents who could get me some data.

It appears that once a limit of 50 is reached things just grind to a halt or slow down considerably. When there are less than max peers (50) on a torrent, it seems healthy and things are progressing yet when max is reached we are back to the old story.

Just my impression from the last two torrents I tried that have been running for over 4 hours now...

[dzontra]

It looks like there will be Transmission 1.0 in near future.

Version 1.00 is just released.
----------
All Platforms:
+ Port forwarding now performed by MiniUPnP and libnatpmp
+ Ability to set global and per-torrent number of connections
+ Option to prefer not using encryption
+ PEX is now configured globally
+ Updated icon
-------------
HNY to all.

[mancub]

...and my hunch is that it's the encryption that's causing all of these problems with low number of peers connected and slow speeds so that turn-off feature in 1.0 will be welcomed. :)

[oleo]

With changeset 7522 (http://trac.nslu2-linux.org/optware/changeset/7522) I've added encryption support which is now turned off by default.
Use config file to change encryption to preferred or required.

PEX is ON by default and cannot be turned off, unless someone will request this feature.

[mancub]

oleo,

Thanks for keeping us up to date with the code. I have upgraded via ipkg to the latest available build (4523) and will report here on the progress. :)

[cvisco]

First, thanks everyone in this community, I learned so much here (and found out how much more there is to learn...)

Now, for the transmission, I am running version 1.0+r4523-1 and my findings are quite similar to this:

I am at 50 peers (max) on two torrents, yet only downloading from 5-10....
It appears that once a limit of 50 is reached things just grind to a halt or slow down considerably. ...

One more thing: when I do flashfs save, directories
/tmp/local/root/.transmission/cache/ and
/tmp/local/root/.transmission/torrents
are being included in /tmp/flash.tar.gz file. This would not be bad if there was no 64kB limit for committing it to flash because it is over 64kB - around 77kB).

Here is example:

What would be the right path to take? Erase cache? Exclude these directories? Something else?

Thanks in advance.

[mancub]

cvisco,

I have put .transmission/ folder with the rest of my source/, work/ and target/ torrent folders, on the harddisk. Then symlinked to it from /tmp/local/root/ and saved the flashfs (and backed it up as well). ;)

[mancub]

It appears that the speed limiter is broken in this last build.

I've set the max upload speed to 50 like I always do and I just saw a torrent being uploaded at 80. I didn't even know my connection could do that high...perhaps it was upgraded to 5Mbit/1Mbit but either way Transmission should not be uploading faster than 50KB/s. This worked fine before...

[oleo]

I do not have such problems with r4567. Upload speed limit is exact!

[Garluk]

oleo please can you add another features to transmission?
I'd like a buttom that make 'http download' directy in target directory.
In this way the transmission package goes versus a perfect download machine.

Thanks in advantage.

[oleo]

Explain more clearly this feature. I do not understand what you meant.

[morfy]

Hi. I compliment for transmission. And' possible to add a script for the download of file http? or for rapidshare free download? Thanks in advance.

[calebz]

Hi.

Perhaps a little tutorial for kamikaze flash + transmission oleo ?
If you find some spare time ofcourse and my router is free to experiment on too ^^


Happy new year btw :)

[Garluk]

Explain more clearly this feature. I do not understand what you meant.

Ok Oleo.

Today the trasmission package allow to manage only the torrent.

I'd like that the transmission package is able to manage also http download and eventually ftp download.
So we have a complete download machine.

Try to look this one:
http://wl500g.info/showthread.php?t=10591

I think that this new functionality is not difficult to be implemented.

I hope to have been clear and to have succeeded in making me understand.

Thanks in advantage

[oleo]

For Kamikaze follow http://www.nslu2-linux.org/wiki/Optware/OpenWRT-brcm24Build

For fetching non-torrent files I need some daemon features or maybe just wget . How to do this without breaking things needs a little thinking. Anyway Fetch itself now works without daemon. So you could easily issue non-torrent URL and get things into $SOURCE. But if you are using thttp then this process will die after 5 minutes. The problem with URL fetching is that is more error prone than torrent. And FTP is an old protocol. Then here is issue of username and password. HTTP fetch often needs cookie session reply. Recursive fetch? Do we really need this? For ftp I use ncftp that can store bookmarks with passwords. wget can be used fetching via http/ftp, but there is also wget-ssl.
I've seen screenshot for wget4web (http://irodov.nm.ru/wget4web). It uses Perl which is not so lihtweight. Managment seems to be poor.

Thanks, this worked very well.

As far as the problem with speed goes, here is the update. With big torrents (4GB+) CPU gets quite busy, and swaping to disk occurs, so transmisson does not update torrent status. I am not really sure, but it looks that at the begining, speed looks good because only download takes place. But after enough data is downloaded to start creating files, router becomes too busy and download speed drops until files are created. After that, speed picks up again but the status is not updated. Hitting Update button helps if downloading only one or two big torrents simultaneously. If there are more big torrents, Update button becomes unreliable - it does not work more often than it does.

Bottom line, in my case the problem was not slow download speed, but rather slow processor/not enough RAM. The router with this software is a great device, but one needs to get to know the limitis. I am still very happy with it and wish to thank all who took part in development.

[oleo]

Status is designed to be unreliable. Queued requests are flushed away. It is non blocking. And it comes eventually. So sugestion for big torrent is that one must take care about memory requrements and not to take parallel downloads .

[morfy]

Hello. I wondered if it is possible to file transmission.conf increase the number of seed to connect. Thanks in advance.

[oleo]

a)Number of peers is limited and not configurable.

b)I've saw that one guy seeds nearly 300 torrents.

Oh ok. But I do not understand why my statistics despite a 5k upload to the meeting with 600mb upload and download 300. :eek: Why? The same with utorrent files downloaded from the PC goes very fast.

[oleo]

Many clients now prefer encryption. Try to enable it in transmission.conf to see if that will help you.

Excuse my ignorance but how do I turn on encryption transmission.conf?
:eek:

[oleo]

Just uncomment the appropriate variable.# uncomment the following if encryption is preferred
ENCRYPTION=-e
# uncomment the following if encryption is required
# ENCRYPTION="-ee"

[avberk]

If you don't see these lines in transmission.conf with a pair of glasses, you might need to update transmission :)

# uncomment the following if encryption is preferred
# ENCRYPTION=-e
# uncomment the following if encryption is required
# ENCRYPTION="-ee"

[morfy]

Thanks. I modify the file transmission.conf and leave a few days to see if connected improves download.;)

[KingGuru]

I guess the encryption thing helped you, but I still have problems with slow speed.
atm I have 3 dl, which I can dl with max line speed in bitlord, but with transmisison (with bitlord stopped) I dl with 1.5k/sec..
It's been like this for a while but I can't seem to find the reason..
any suggestion except the encryption thing.. didn't help me

KG

[bogd_A]

same problem with slow downloading speed.
encription - didn't do the job

Now I have one torrent of 8,3G, 50 peers, dl from 14 at 32 - 40kb/s, and the number of peers from which I'm downloading from is max 14.
same torrent on my PC - 800kb/s - 1,2 mb/s.

Don't know what to try.

[Serpent]

As I already told you, try rtorrent. Believe me, is worthing!!!
You have the links to the relevant threads.
But if you want an "step by step HowTo", just ask here... :D

I will try in this week-end to install rtorrent, and a step by step How to will make my day, considering that my first contact with linux happened about one month ago when I bought my V2.

If it helps I use 1.9.2.7-10 oleg's firmware, and followed wengi's tutorial.

So, thank you in advance.
