I was looking into this.
The nice (start a process with high priory) binary doesn't exist for busybox, so what you can do is use renice (change a running processes priority).
renice is a bit odd, I haven't figured it out.
But you can make a script that will start vagalume and renice it and edit sudo so you can renice without a password (you need to be root to set high priority) and then edit the desktop file to run that script.
But of course, you will have to enter shell to set it up.
Another way is to edit sudoers to let you use renice and set up a renice command that you run after vagalume is started via a personal menu or osso-status bar.

i have also thought of adding a command to osso-status bar.
but don't I need the process id, when i use the command?
or doesn't the pid changes after a restart of an application?
So I can't do it without a script, right?
do you know how to find out the pid of an application in a script and insert it in the renice command?

Oh yes, I remember that :P
Basically you can do this in your script:
vagalume && renice <insert all the right stuff> `pidof vagalume`
``'s in a script execute a command as an artument, pidof vagalume returns the pid of vagalume which renice uses.
So the pid doesn't matter.

Somehow the output of "top" and "ps -axl" doesn't show me the priority of the processes.
So I don't know if it worked right, because I have still a lag in music playback.
Maybe the reason is the lack of memory.
I get the following output of top:
Do you know why the %MEM values are so high? If I sum them up I get more than 200%.
Is it normal that so much memory is cached?

I'm.not sure. Vagalume is.streaming so there may be network lag.
Here is my output on a cleanly flashed N800:

i don't think that it is a connection problem, because it occurs only when I do something in other application. Sometimes even if I only want to ractivate the background light and click on an empty place on the screen.
But this is only if i have other applications running.
So i think it has to be CPU or memory.

You can find the PID of your applicaiton with the following command:
ps | grep <your_app_name> | cut -b 1-5 | head -1
Hope this helps,

I searched for it, but i didn't find a solution.
Is it possible to start media-players (i.e. vagalume) with high priority, so that it will not be interupted while playback?
Because if I do some other things the music sometimes stops playing for a few ms.
And if it is possible, can I add an icon to do it easily without entering the shell?
thanks for your help...
