[LAU] limits.conf nice rtprio

Hi, I am afraid that I still don't understand limits.conf file properly. Hopefully someone can explain me some details. I have limits.conf file like this: @mira - rtprio 99 @mira - memlock 8000000 @mira - nice -10 @mira /usr/bin/jackd nice=-1 rtprio=85 @mira /usr/bin/qjackctl nice=-1 rtprio=84 @mira /usr/bin/ardour nice=-1 rtprio=83 @mira /usr/bin/hydrogen nice=-1 rtprio=82 @mira /usr/bin/jackeq nice=-1 rtprio=81 @mira /usr/bin/jack-rack nice=-1 rtprio=80 . . Should I do something better with nice and rtprrio values to ensure better RT robustness ? There is also possible add "priority" value in limits.conf file ... Should I use it? 2nd question: In qjackctrl Settings -> Advanced ... there is a "Priority" option ... How it is connected with these above? Should be used? mira
