Re: process in background
Some more data as suggested. I run without nice, with nice -n 5 and nice -n
10, each version twice:
CPU% according to top reached 118%.
nice -n 5:
CPU% according to top reached 147%.
nice -n 10:
CPU% according to top reached 131%.
I do not trust the accuracy of top; I only use it to see relative CPU usage
of processes running *at the same time*. The above results speak for themselves.
However the cpu usage reported by 'time' shows that nice incurs a hefty
penalty even though the system does nothing else.
I stress that I do not think that the above indicate a problem with nice.
This maybe just how it works. I think I need something other than nice to
tell the system that a process should be given all the spare cycles but
Every hardware eventually breaks. Every software eventually works.
