Low speed on NAS

[DHMH]

Hi,
I got a big problem with transmission(-daemon) and my NAS.
I try to download a torrent, on my pc with uTorrent I get a speed of around 1,2mb/s.
At my NAS it's only 20kb/s using transmission.
Port is forwarded correctly.
Heres the output of "top":

Your settings.json file, transmission version, and what kind of nas you are running might help..

However if I was going to guess by your top post that you are running some kind of buffalo brand nas.

Remember your nas has a pathetically slow CPU and less ram than your PC running uTorrent. Allowing too many connections at once will kill it. Also transmission doesn't limit how many active torrents there are, just connections... So if you have a pile of torrents in open at ones it will spread the connections over all of them instead of focusing on a few of them at once.


Try tweaking the following settings, remember you need to KILL / Stop the transmission daemon BEFORE editing and saving the settings.json file or it will be over written.

"dht-enabled": true,
"encryption": 1,
"peer-limit-global": 150,
"peer-limit-per-torrent": 50,

Thank's for your reply.
I'm using a Buffalo Linkstation Live with 1TB RAM.
I think it has got a 600MHz processor.
I installed transmission through ipkg.

I tweaked the config, but I'm getting a speed of 10kb/s ?!?

Try turning down the "upload-slots-per-torrent" to just 2.

How fast is your internet connection? Your speed limits look all wrong as these are set in BYTES per second (used by the OS for file transfers) not BITS per second (used to describe network transfers just about everywhere)

Your normal speed setting right now would be 800Kbits / 800Kbits your alt / turtle settings would be 400Kbits / 400Kbits . This seems odd since most home internet connections at least in North America have more download than upload.

What is your speed reported by www.speedtest.net?

Note that setting your upload too high can really kill the connection and degrade download performance.

My normal speed setting are
"speed-limit-down": 512,
"speed-limit-down-enabled": true,
"speed-limit-up": 20,
"speed-limit-up-enabled": true,

Or 4096Kbits down and 160Kbits up

My line speed is actually 7Mibts down and 512Kbits up but I keep a buffer so that Transmission doesn't kill all other traffic on my home connection

[DHMH]

I got DSL 1000 and my DL Speed is normally 120kb/s ..
Why should I enable the speed-limits?
Now the speed limits are disabled, so whatever I set as speed limit should not be used
I set the upload-slots-per-torrent option to 2, and now i will need to check, if the speed has changed.

EDIT:
mmh.. seems that that changed the speed a little bit.
Now my lowest speed is 20kb/s and my highest is 120kb/s.
but: It fluctuates a lot.
So most time the speed is ~50kb/s.

[DHMH]

mysterious..
Now my speed is about 70kb/s .. sometimes 110kb/s..
Should i set upload-slots-per-torrent to 1?

ahh and I forgot to mention that I disabled the "blocklist-enabled" option.

[Longinus00]

What you should try is to limit your upload and download speed like lazybones suggested and put upload-slots back to something sane like 5 or 6.

[Spadge]

I pipe mine through dummynet to limit total upload of transmission, not just the torrent upload.

Because every protocol has overhead. TCP/IP uses upload to get downloads, so the faster you download the more upload bandwidth gets used. Transmission does not include this overhead in its max upload speed setting.

My upload runs at a pretty steady 90KB/s except for when I'm downloading heavily, because transmission is only allowed a maximum of 110KB/s up to the internet.

If you don't limit your upload and download to within reasonable levels for your bandwidth you run the risk of killing internet performance for every machine on the network.

1. What are your www.speedtest.net results, as noted you have not reduced your upload bandwidth..
2. You could reduce to 1 however if your upload bandwidth is still set to high it won't matter. I think 2 slots is rather fair for those of use with very limited upload bandwidth.

[DHMH]

I set upload-slots-per-torrent to 1, and now I got nearly fullspeed.
(but only "nearly": 110kb/s max, 90kb/s min)
Here are my speedtest.net results:

[lazybones]

Wow your upload speed is tiny

Try setting "speed-limit-up": 10 this will be 80 kbits/s

Your last setting of 100 is several times more than wha you actually have

[DHMH]

I set everything as you said, but the speed is fluctuating a lot!

EDIT:
I'm not getting 110kb/s constantly.
Is that normal?
On my PC with uTorrent I get 1,2mbit/s and that contant..

[lazybones]

Yes, I would say fluctuation is normal. Also I found I had better performance with utorrent, however on my NAS I mostly use flexget to start torrents and I don't sit there watching them download.

[axishero]

I also use 1.93 in NAS.Speed is ok compared to Utorrent in PC.But the verification before download is too slow.
