i'Ll save your snippet to my growing %%% awk file in my ~/HowTo,
thankee much. I'm in the first stages on a months-long trial on
system tuning. This, before I'd risk publishing anything. So
far tho, by upping and lower the NICE prio of various binaries, I
have been able to get more than 70% efficient use out of my older
servers. ---This *ought* to carry over to my faster machines....
Is tthere a way of using ps -alx | ask to look at nice and if it
is non-zero (the default), to reset it to zero?
You can easily do some of this using top, such as:
top -bS 200 | tail -n +9 | awk '{ print $5 }'
If you want to tweak the nice value you'd need to examine the value and
then renice it as long as you are root. You'd need the PID for that, so
here's another example:
top -bS 200 | tail -n +9 | awk '{ printf("Pid: %d has Nice: %d\n", $1,$5) }'
