Hi all,
I have several NAS systems with different specs, one of them is a NetworkSpace 2 from Lacie which has a ARM 800 MHz CPU with 256 Mb. Altho that's not a powerdevil, the device functions pretty well.
I don't run the LaCie software anymore and now run Debian Squeeze on it, and installed SAB on it, however, it performs horribly.
My question is if there are any optimizations I can do to make it run better.
I have a UPC 120 Mbit connection, being able to download with 14 Mb/sec and on my desktop that's manageable, however, on the NAS it won't go higher than 3,4 Mb/sec. When running "top", i see the python process taking 100% CPU. (a simple wget reaches 14 Mb/sec on the NAS)
When the download is complete it extracts pretty faast for such a box, so that's ok by me, but seeing the Python process taking the full CPU with only 3,4 Mb/sec is not that good.
Are there any tweaks I could perform to let it run a bit faster?
Thanks in advance!

Re: NAS Optimizations
SABnzbd is very CPU and memory hungry.
It seems worse when you have particularly large NZBs,
which is something we're going to look at in the near future.
Do you have a compiled _yenc.pyd on your box (the log tells you at startup) ?
If not, there will be a heavy CPU penalty.
Other than that there isn't much else to optimize.

Re: NAS Optimizations
What I see at startup is this:
Assumingly I have that installed?

Yes, you have the _yenc.pyd module.
Re: NAS Optimizations
Thanks for checking, too bad there aren't any optimizations I can do for this box...
