Hi Bob,
yes I know about nice and if I will not find an other solution I will use it for increase priority of other processes..
Thanks anyway :)

Just for interest Fabio did you try nicing? (Changing process priority)

I don't actually nice the motion process, but that same box is also a
squid proxy that I increase priority for. I also create motion avi
movies every hour and do my nightly backups both niced. Works well.
