Changing "Nice" value to eliminate CPU spikes?

Post by bradycline »

Anyone else following this thread on logicprohelp.com ?

The good stuff starts here: http://logicprohelp.com/viewtopic.php?t=16909&start=11
"...it is just telling scheduler (the OS part that gives CPU time to processes/threads) - to favor Logic, or anything that has high priority. ..."

They are ecstatic over there with the success they are having eliminating CPU spikes/overloads - something DP users would love too. Have you already tried this with DP? Could be great for us too.

I do this with very large sessions, but for average sessions I don't. I used to do the same with Pro Tools.

It's a standard UNIX utility - but it resets itself after the program is quit or a logout or reboot occurs.

Please be aware YMWDV when you start to play with Nice...
Just because "this" project works great, doesn't mean that project works as soon as you add a new plugin or VI to your project. Also, if you are too adventurous playing with nice, you may have to do a reset or wait well into next week in order to save & quit DP.
... said someone who was too nice once in the olden UNIX days...


On the other hand you just need to restart DP (or worst case, reboot the mac).

Nice simply sets a priority for the process in question - it's really not dangerous if you are only playing with processes in userspace (non-root or system level processes). The priority range is -20 (highest priority) to 20 (lowest priority) with standard priority being 0.

The great failsafe is that Nice is temporary and resets after the process in question has been halted (quitting DP for instance).

Of course, when playing in terminal you want to be careful, but nice is one of the more benign utilities. Not nearly as bad as 'sudo rm -r *' :shock:
