New Transmission add-on thread

Ah, shame there is no difference. Its is prob more to do with the speed / traffic coming in rather than connections.

I did notice high CPU (almost max) usage at first when running 1.72 months ago, I was concerned at first, then I forgot about it lol.

Using 2.01 now, but I can't seem to get my port opened correctly, the old version opened it fine, so I might go back. Could just be my router bing stupid though.

it doesnt seem to be speed related.... 400kb/s or 1.25mb/s+ - same CPU time, so i'd of *expected* it to of maxed out based on cpu load but that doesnt seem the case.

i wouldnt mind the high CPU time (no noticable increase in power draw), but it's slowing down the entire duo box, and for a unit that isnt that powerful or fast in the first place, it's irritating. i think i saw down to 5-10mb/s cifs transfer with transmission running (~500kb/s throughput). usually get 20mb/s+.

so much so, i'm debating flogging my duo and going for an ultra4. (it's a shame they dont do a 2 disk x86... DUO-PRO or something :)). that said, the readynas OS is limiting me a bit too, so i might opt for some older hardware and run a full blown OS it... linux or windows...
i wouldnt be limited to the work our 2 most active devs do either... SP and whocares?.
i dunno. i need more info on everything - is transmission at fault, the duo's limited speed, if i move to x86 will i suffer from similar issues, and why spend £400, when i've got spare hardware i could cobble together and have a box thats alot more powerful and versitle than a readynas.... albeit after spending lots of time to get it setup, physical size and power consumption....
choices choices!!!

seems to be the quantity of torrents thats causing high CPU time.... which im guessing is completely normal and the duo is just more underpowered that i realised.
3 active torrents and im running around 40% cpu time.

i might reside the duo to backup perposes and go either a RN ultra, or a custom PC build route. it's starting to look pretty obvious the duo isnt upto the tasks i thought it'd do!

I'm running Transmission 2.0.1 on a Duo.
Currently I'm seeding 103 torrents (total size 285GB) on 5 different trackers, of which at the moment 3 torrents are uploading (filesize each 6-7GB).

CPU usage of Transmission is mostly between 10% and 35% with peaks up to 60%. I'm checking this with top via SSH.
I don't really bother about this cpu usage, since AFP and HTTPS seem to have higher priority and therefore I don't notice anything during streaming or downloading.

Just giving you my usage profile as a comparison and I don't think that quantity should be of concern with just three torrents..
Don't get me wrong, I Iagree that the Duo is underpowered, but Transmission does work like a charm. And why not let it use 40% of the CPU anyway? There's still 60% left. :)

edit: Just read about your CIFS-issues. I hardly ever use CIFS and mostly connect the Duo over a 8011.g wireless network, which yields nothing close to 20MB/s anyway.. Whenever I move something to the Duo though, AFP gets most of the CPU and Transmission is suppressed.

thanks for the info daniel.

good to know what your experiencing.
40% is ok for me, doesnt seem to impact CIFS shares enough to notice. but like you say, 3 isnt something to worry about; i should be able to have more active files.
PM sent since it's outside the scope of this thread...

i think i've got it!!
various tweaks done, not sure which one fixed (in the order they popped into my head when writing this)..

- disabled watch folder temporarily (stop service, edit config file, start service and left it for 20mins and then re-enabled)
- reset permissions on all user data locations that transmission used. for me this was media & data shares. owner was the folder name, group was 'nogroup'. transmission was stopped while permissions propogated.
- add in '\' before any '/' in the config file for any folder locations. ie: '\/c\/data\/torrents'
- rename config file to .old and reinstall transmission; config file recreated.
- setup network connection limits in config file, using http://forum.utorrent.com/viewtopic.php?id=58404 as a guide. for me on 700kbit/s upload, this was reduce the pre-defined limits by around 20%.

transmission now ranging between 40-60% cpu time on 18 download, 12 seeding with a user-set limit of 250k down, 50k up.

currently using 2.01 final.

thanks for all your help guys - looks like with a 'benchmark' from other users experiences and performance claims there was something was up with my box which i've now fixed!

im wondering now i've set the permissions correctly, if this may have a bearing on if torrents will keep their status or not (in reguard to SP's start/stoptrans.sh scripts) - time will tell on that one.

Hi there!
I have little problem since transmission 2.03 was installed. Now, even if I install 1.92 version I still have error message -
"populateDivFromUrl /addons/TRANSMISSION/TRANSMISSION.jseval error caught SytaxError: unterminated string literal"

And I can't stop transmission add-on or remove it because the 'apply' and 'save' buttons are gray permanently. Transmission interface button don't work.
Although add-on work correct when I use remote gui, it will be good if somebody can help me with this problem...

i just wanna try the obvious; have you rebooted your duo, then tried reinstalling 2.03, and then see how it acts in frontview?

Yes of course. I did as you said. I tried to reinstall add-on and for 'best installation' i did reboot after this every time... but this problem still there

can you give me ssh access to your unit ?
