Keep XBMC playing and download without problems tweak

[wilcoo]

I use this tweak (kernel.sched_autogroup_enabled = 0) and now i dont have to shutdown or pause the downloads and nice work great no more hickups.

What to do:
First change the kernel scheduler

sudo sysctl kernel.sched_autogroup_enabled=0

sudo reboot

After that you can change the priority of the download process (NzbGet,Transmission)

sudo top -u xbian

Find the PID of Nzbget|Transmission and press r (renice) fill in the PID after that 5 (Higher is lower priority)

You can do this again for couch/sickbeard/headphones set it on level 6

If you want it every time it's boot up then look at this:
start-stop-daemon > look for this " -N, --nicelevel int"

Here is the reference where is got the idea.

And work from the usb hardisk the easy way and no need for the SD only for boot.
