I'm still getting high CPU usage with 1.51, with just 3 torrents going. Is anyone else seeing this?

i dont know if its high cpu usage but it seems something is 'stopping' once in a while, when it happends a transmission-remote -l just pauses and give
no output, webgui doesnt work, then after a while its available again.
i have a 30mbit/30mbit connection so it might be harddisk is getting busy when some new torrents are added, the dns-323 are connected directly into
the 100mbit switch/router so it should'nt be a local lan bandwidth issue either.

I have just installed and tried transmission and i feel the upload rates are a bit low? anyone have any similar experience?, with 10-20 popular torrents
running and 30mbit uplink, total upload rate gets to 2-300kb/s and its alot of ups and downs, like from 300kb/s in 4 secs and down to 1kb/s then after 10 secs its upto 300kb/s and so on...

Hello,

I have just installed my first transmision 1.51 (no never older versions) and have CPU usage about 40%-48% downloading 4 and seeding 12 torrents and having 40KB/s down speed and 380KB/s up speed. I think this is too high comparing to MLDonkey which I have used before. Is it normal or is it some issue ?

Tried all 3 but no success

I just had the same issue. I added torrent and get this error. Then created folder and still got error. Then I deleted torrent and added again and everything went ok.

Hi,

I have installed Transmission (followed instructions at http://www.shadowandy.net/2009/01/trans … ns-323.htm) but when I add a torrent via the web interface, it fails saying "no such file or directory". Can anyone provide advice on where I am going wrong?

Thanks

By default, when using the transmission.sh start script, Transmission is running in the userspace of the user "nobody". You have to make sure that all files folders Transmission acesses must be owned by this user. This mainly goes for the config folder /mnt/HD_a2/.transmission-daemon, and the download folder as well.
The first is created by Transmission automatically when it doesn't exist, so for new users this shouldn't be a problem. But the download folder has to exist already, and must be accessible by the user "nobody".

I'm surprised about that, alpha. Back when I tried MLDonkey, it was a really memory hog and used lots and lots of CPU cycles. I then tried out some other torrent CLI app I don't remember. After that I discovered Transmission, and it uses by far the fewest resources of all of them.

And now, I don't have a RAM mod :)
64MB is all that's available.

For the people still seeing high CPU usage: please consider that the NAS is powered by a measly 500MHz CPU and has only 64MB RAM (part of which is actually reserved by the OS). It is not made for serving data (via BitTorrent) to many users. I advise limiting your number of torrents (especially downloading ones). I think 5 is a good limit, but YMMV.

500Mhz is not "measly". Just a few years ago, people were running windows 2000 on 200-300mhz cpu's with only 64MB of ram.

From microsoft's website:

"Before you install the Windows 2000 Professional desktop operating system, make sure that your computer meets the following minimum system requirements:

    * 133 MHz or more Pentium microprocessor (or equivalent). Windows 2000 Professional supports up to two processors on a single computer.
    * 64 megabytes (MB) of RAM recommended minimum. 32 MB of RAM is the minimum supported. 4 gigabytes (GB) of RAM is the maximum. "

The DNS-323, doesn't even have a graphical environment, so it's not like it's wasting memory/cpu on that..
It's a powerful machine, it has the capabilities, it just needs decent software to run on it. (I'm not saying Transmission is not decent).

Hi Kylek!

I download the new 1.51. and make a fresh install. (I change the harddrive so I make new ffp, etc).
Iit is works great with the old torrents but if I try to add a new torrents it stopped the download process stopped with message: Permission denied.

With 2-3 torrents running my CPU averages around 20%, with infrequent spikes to 45%. Download is as fast as the peers allow, up to 1.2MB/s, which is my line's limit. I haven't observed the CPU usage at those speeds, however. It might be higher because of the increased I/O operations.

how will i check if im also getting a %100 cpu usage? what command should i type? Thanks.

seems like normal on my end. %15 on mine (if im reading it correctly). Transmission 1.51 w/ 25 seed and 3 download.

question, why is it that there are 3 transmission running? is this normal (below)?

^^ i dont have a fast connection but if you still wanna know my download is 200-240 KB/s and upload of 60-80 KB/s

I'd say that's normal. Remember, Transmission does have no form of caching (either for read or write operations), so for every packet sent and received the drive is accessed. The faster your connection is and the more torrents you have open, the more I/O operations are performed, which puts some form of strain on the device.
