Sabnzbd not using full bandwidth.

[manpreet]

I was running sabnzbd on Windows 7 and it was using full 24Mbps but i migrated it to debian, and not I am not getting more than exactly 1.1 Mbps, its like there is a limit set somewhere.

You have an article cache set?
It should run faster on Linux than on Windows (on comparable hardware).

Don't you mean 1.1 MB/s?
I got the same issue as you, but I got both IPTV and VOIP that steals bandwidth, or did it go faster when you ran Windows..?

[manpreet]

There is not Article cache set. There is nothing else downloading at all. And I mean basically is hould download at 3 Megabytes/s but only doing at 1.1 Megabytes/s

Set an article cache. Currently a lot of time is wasted on disk access.
Set it to 200M if you can afford the memory use.

Allow me to hijack threat for a simple question. I have 4GB of Ram and article cache set to 256MB, running SAB on full speed of 4MB/s. Where is limit of cache size? I mean, should I set it to 512 if I have often many jobs in queue? I don't have any performance issues so is it worth it?

[shypike]

A cache that is large enough to take one complete file (plus a bit extra for the next one)
will reduce the disk access quite a lot.
Generally 200M is enough.
The choice is yours, SABnzbd will function either way.

So I set it up to use 2048MB Article cache (host has 16GB RAM) but its still working on same 1.1 Mbps, I am ready to pull my hair out cant figure where its choking

I understand your frustration, but I cannot tell you where the issue is.
Whether inside or outside SABnzbd.
To add to your misgivings: I run SABnzbd on an old netbook running Ubuntu 8.04
and I can get between 6 and 7 MBytes/sec.
So far all Linux/Unix variants I ran under VMWare have similar or better performance.
What I cannot vary is my router and ISP.

Which Debian do you run exactly?
Did you install the Python-yenc package too?

Throttling?
Poor peering?

Sometimes there are random events that affect speed. Good luck.

[manpreet]

It issue is it was working perfectly fine when running on Windows.

I do have python-yenc package and using debian testing

Finally fixed the issue apparently kernel 3.1.0 MArvel Yukon drivers auto negotiate at 10Mbps even with 1000mbps cards so to fix

ethtool -s eth0 autoneg off speed 1000 duplex full

Glad you found a solution.
But I hope you understand that it's impossible that we (developers) come up with such a solution.
Sometimes fellow users can suggest such solutions.
