Re: {Snake OS} Is this alive or has it been stopped? Transmission Issue

[Iuri Guilherme]

It seems that this is completely unrelated to your hard drive.

It seems that it has to do with the networking. You have tried the same
ethernet cable and the same whatever-everything you use with your
desktop with the snake-nas and got the same result? Also, are you
monitoring this bandwidth usage from within your router or other network
traffic measure device, or are relying on whatever appears on your
transmission web interface?

[OmarV]

I am just checking what appears in Transmission Interface but I see what has been uploaded in the tracker and it is too poor.

I tried with two different links with same result and in PC with Wifi, never with LAN but it should be related with Lan...

Is there any way to check Snake speed? I mean, without Transmission.

I have no idea what I can do more... :-(

Any Transmission parameter?

[Iuri Guilherme]

It seems that you have a modem with a wifi router, so you could measure
the bandwidth and/or the traffic from within the modem/router. Also, try
to use ethernet cables on your computer to see if the problem is with
the cable itself.

The NAS usually have a 10/100 ethernet device which could be slower than
a wifi connection that handles 300mbps. But this shouldn't be a problem
if you have a dsl connection to the internet, because it doesn't make
any difference anyway. You could have a problem if you have a fast
connection like optic fiber for instance.

[OmarV]

I will try to check with my PC using ethernet.

The connection is 30MB optic fiber, this is why I don´t understand the speed... The NAS is a basic one but I know that other people download with Transmission at 1Mb or more... Why mine is so lazy?

[OmarV]

Hi again!

I checked ethernet with PC and uTorrent goes very much faster than Transmission. I checked with DMZ as well with same result.
UPnP enabled? where? how can I check that?

Could it be related with "Encryption Mode"? I have "Require encription" now. Can somebody show me his transmission properties? :-D

I have no idea what can I check more...

Thanks!

Just a quick thought, have you checked your port(s) are open?

Quickest way to check would be to TEMPORARILY put the NAS in your router's DMZ. Reboot router if necessary. If your speeds jump up to closer to your PC's torrenting speeds (don't forget to leave the torrent downloading a few minutes to check properly, oh also for the purpose of testing, choose a torrent with a lot of seeds), you have the problem. Remove your NAS's IP from your router's DMZ (not secure otherwise). Either manually add the port in your router's port mapping area, or check whether UPnP is enabled.

Apologies if this turns out to be a wild goose chase, but worth excluding as a cause to your problems.

Hi.
I
I have the latest version (20111019) with 2.60 Transmission version. I do not why but if I download any torrent from my PC, it goes faster than in the Transmission. It cannot go faster than 400k in the Transmission when in the PC it goes about 1Mb...
And not just the download, the upload is really so so low. Some times it goes around 15ks, sometimes it stops... This is a pity to be a member of a private tracker...

Could it be related with the HD? I am using a external HD with this config

Hi!
I think our snake device has not enough resources to handle a torrent with many seeders.

I agree with Rafael, you should limit the total amount of peers wich transmission connects to (global limit), and per torrent limit.

Also, check the last one (I think is the last, as I haven't checked for more than 1 month) from groups wich have an script to auto restart transmission when it hangs.

Also, 2 months ago I also did a lot of holes to the plastic case of device.



Check my stats:
# uptime
 10:40:30 up 6 days, 15:45, load average: 0.26, 0.07, 0.02
# top
Mem: 29296K used, 1148K free, 0K shrd, 1008K buff, 8876K cached

Load average: 0.44 0.14 0.04 2/35 22143
--cutted--



But transmission says (on statistics) 6 Hours. So for me is working quite well.

Limit per torrent: 4 peers
Limit global: 10

And limit in speeds too, because I wan't to be able to surf the web during the day, and have only 3MB download.

[OmarV]

I have

Limit per torrent: 60 peers
Limit global: 240

I am changing to

Limit per torrent: 8 peers
Limit global: 20


I have no download limit because I have a 30Mb download and Transmission goes around 400ks... I would like to have to limit it because it eat all my download line :-)

My statistics:

Kernel version:	2.6.16-gazineu
NAS version:	SNAKE OS V1.3.2 (20111019)
Storage Name:	snake
LAN IP Address:	192.168.1.16

And what about the encryption mode?

Regards and Thanks!! :-)

[pepe]

>>And what about the encryption mode?

I have It enabled, I mean, "Prefer encryption".


Hope that now it runs faster, and you have to limit its spedd, :)

(But just in case you don't reacht the limit, check that your ISP doesn't apply QOS rules)

[OmarV]

Bad idea. Now it doesn´t download any :-(

Back to the previous settings...
QOS is not applied.

:-( Any more help?

You did allow some minutes before giving up?

[OmarV]

Yes of course

I waited a night...

And putting back peers at 60 per torrent and 240 total did help?

[OmarV]

Download 400ks (I have 30Mb Dwnd/1Mb up)
Upload near 0Ks...

What can I do mates? :-(

[OmarV]

These are my statistics

Total

This is still odd.

I have the same results whether I use the snake transmission or the
64bits transmission on the desktop.

I am still convinced that it has something to do with your network setup.

I'm gonna find out what the encryption means and test it here.

[Iuri Guilherme]

Actually it seems that our friend OmarV has a real issue and the
download speed is really capped at 400kbps.

Now I wonder if it is a kernel limit, because it can't be related to the
usb port.

Anyone tampering with the kernel source?

[Iuri Guilherme]

I have reduced the peer limit to 20 global and 8 per torrent,

Have disabled encription,

Have enabled port forwarding,

The download rate still is capped at 380-400kbps.

The upload rate seems to be unaffected. I have only 400kbps of upload so
I can't tell for sure.

The issue seems to be the flash memory write time that caps the download
rate. It may be a hardware limitation or even a kernel hardcoded
limitation (which in the end works the same way).

[Stefan Scheffler]

I never get much more than that either.. even on a lan. It may have to
do with how torrents are transferred in small chunks. Which means more
work for the storage driver. With other protocols and I get up to
5-7MB/s.

So nobody can download by Transmission faster than 500ks?

And what about the upload?

[Francisco Figueiredo Jr.]

I also noticed that.

My theory is that NAS cpu isn't capable of handling so much encryption work and so it isn't able to process so much data. You can check that by executing top in a console or checking transmission status that the cpu keeps at 100% all the time.

Under the same connection, when I started to use uTorrent on a netbook instead of NAS I could use up all my connection bandwidth.

Just my $0.02

[Gabriel Fernandes de Almeida]

That's correct. Time to create a snakeos Cluster Edition, to make it more scalable :p

Engra�ado :D

Most people would thank snake for the bandwidth cap without the need for
any network device configuration :D

Most people have to turn off torrenting because it eat up all the
available bandwidth by default and most times there's nothing one that
doesn't know much of networking can do (which has been solved, but not
quite, with modern torrent clients that give the bandwidth limit option)
