=================================================
trace-bonnie.sh : start bonnie++ process for 10s
time statistics:
real 0m10.715s
user 0m0.420s
sys 0m6.350s
lttv statistics:
events count : 11088588
cpu time : 80.051904112
cpu time should be good. How many cores does you machine have ? 8 ?
Thanks for explainations. Yes, the system has 8 cores. The maximum CPU
time for 1 second is hence 8 seconds.
=================================================
sleep 1s : start a sleep of 1s
time statistics:
real 0m1.002s
user 0m0.000s
sys 0m0.000s
lttv statistics:
cpu time : 7.841686487
How then can we explain that on an idle system, the CPU time is yet
(almost) the number of CPUs times the trace duration?
Cheer,
Francis
