Code:

sudo nice -n 15 /etc/init.d/nzbget start >/dev/null 2>&1 &

To add info: You can also change the priority of existing processes using renice, for instance for changing the priority of samba:

Code:

sudo renice 10 `pgrep smbd`
sudo renice 10 `pgrep nmbd`

Also, I have been told that you have to run the following before these priorities will have any effect, don't know if this is (still) true.

Code:

sudo sysctl kernel.sched_autogroup_enabled=0

Without the kernel.sched_autogroup_enabled it wont work.If you want to work without problems and you need to resize the swap otherwise you got problems with out of memory closeups. (i have 512Mb for swap on my RPI 512).
