Lower unrar cpu priority

Post by Vorkbaard »

When I'm watching a film with my mediaplayer it jitters and halts when SABNzbd is unpacking a rar set. My mediaplayer is streaming from my download server so that's not really surprising.

Is there any way I can lower the unrar function's cpu priority for SABNzbd?

Thanks!

The problem is probably not the CPU but the disk channel.
When running on Linux you can experiment with the "ionice" settings in Config->Switches.
Otherwise, disable post-processing during the times you watch TV.
(Scheduler option).

Sorry, should have mentioned I'm using Windows Server 2008 R2 and the latest SABNzbd. And you're right, it's the disk, not the cpu.

However if I can slow down the unpacking process this would help a lot, I think. I do disable post-processing like you suggest but I'd rather have it fully automated ;)

Thanks for your answer!

I know of no methods to tame unrar further.
It has CPU settings, but not IO settings.
BTW: the same problem occurs for par2, potentially worse.

Think I'll try unpacking to a big usb key then. I'll let you know how that works out. Thanks for your time.

But as soon as you start copying to the hard disk, you get the same problem.
You might as well just postpone post-processing to scheduled times.
