Asrock Ion 330 - unrar extremly slow

[camelrider]

Hi

I have been running sab on my main machine without any problems but decided to move it together with sickbeard, couchpotato,headphones and mylar to my xbmc machine as this one is running 24/7

Installation and setup worked like a charm - first downloads from the various apps came in - everything seemed fine but as soon as the files are downloaded the unpacking process takes ages (8gb film is already in the unrar process for more than 8 hours and still not done)

Is this behaviour to be expected as the asrock ion is not the strongest?

Asrock Ion 330 running on Win7 32bit - Intel Atom CPU 330 @ 1,6GHZ - 2 GB Ram (0.5 GB reserved for graphics)

Has something went wrong during installation?
Are there any tweaks i can apply?
Is it based on the unrar feature of sab and i should switch to a postprocess script that unrars the files?
Should i switch to Win7 64bit?
Should i switch to Linux and if yes which distro (must be capable of running sab, sickbeard, cp, headphones, mylar and XBMC)

I'm clueless to be honest

thankful for any hints, tipps and tricks

Is this a local hard disk?
Not an USB or network one?

[camelrider]

unrar should run still on local drive - cp and sickbeard than use their vodoo to transfer it to a nas drive but as those scripts only start after unrar i dont assume any impact on the slow unrar process

Have you tried how unrar (or full WinRAR)?
More people have complained about unrar performance, but there's nothing we can do about it.

A later release will support 7zip, with an option to use it for unrar as well.

thanks for your help

Any idea whether e.g. open elec would improve the speed (or any other linux version)? never tried linux before ...
Or switching to win7 64bit or even win 8?

SABnzbd is much faster on Linux than on Windows, given the same hardware.
I don't know if the same is true for unrar.
OpenElec is a great, no-hassle solution, although I haven't checked whether they keep up their SABnzbd releases.
Beats Windows as a media player hands down.

i will give ubuntu a try as most of the apps/addons i need are supported and if this works out as expected i will give openelec a try (although i dont like not to benefit from new versions of sab etc as they have to update their addon)

thanks a lot

if you or anyone else has another advice for a linux distribution do not hesitate - it seems i will do a lot of installing/trial and error in the next weeks

FWIW

par2 and unrar take a lot of processing power. So that means a long processing time on a low-spec CPU.

For example, on my HDX with a 400 Mhz MIPS, the proces can half a day for a DVD. But the processing time varies. Maybe it depends on the amount of errors which need to be corrected?

If I can find time, I can test a DVD download on my netbook, which has an Atom CPU too
