Hi Brian, I know that job priorities can be altered, hopefully the below is of help to you.
Regards, Phill. Kernel decides how much processor time is required for a process based on the nice value. Possible nice value range is: -20 to 20. A process that has a nice value of -20 is very high priority. The process that has a nice value of 20 is very low priority. *$ ps axl* Use ps axl to display the nice value of all running process. F UID PID PPID PRI *NI* VSZ RSS WCHAN STAT TTY TIME COMMAND 4 0 1 0 20 0 2100 724 - Ss ? 0:06 init [2] 5 0 2 0 15 -5 0 0 - S< ? 0:00 [kthreadd] 1 0 47 2 15 -5 0 0 - S< ? 0:00 [kacpid] 1 0 48 2 15 -5 0 0 - S< ? 0:00 [kacpi_notify] 1 0 125 2 15 -5 0 0 - S< ? 0:00 [kseriod] 1 0 166 2 20 0 0 0 - S ? 0:00 [pdflush][Note: 6th column 'NI' is the nice.] To increase the priority, give a lower nice value as shown below. However, only root can increase the priority of a running process, else you’ll get error messages. *$ ps axl | grep test.sh* 1 0 12345 2 15 10 0 0 - S< ? 0:00 test.sh[Note: 6th column with value 10 is the nice value for the shell-script.] Now decrease the nice value to increase the priority of the process. Use the PID of the process. *$ su - # renice -5 -p 12345* *$ ps axl | grep test.sh* 1 0 12345 2 15 -5 0 0 - S< ? 0:00 test.sh[ Note: The 6th column now shows a lower nice value of -5 (increased priority)] On Wed, Aug 11, 2010 at 1:11 AM, Brian Redfern <brianwredf...@gmail.com>wrote: > I wonder if optimal audio performance gets in the way of other desktop > features?
