Comment 26 for bug 1773959

Regarding:

% time seconds usecs/call calls errors syscall
------ ----------- ----------- --------- --------- ----------------
 83.37 2.716542 2 1494072 clock_gettime

I believe that's 83.37% of the process' system time. It's not the overall CPU usage of the function. If you use the 'time' command or compare fields 14 and 15 in /proc/PID/stat then you will likely find the process' system time is not a significant percentage of its overall time used. Because that doesn't include the 'user' time which is a much bigger fraction. So the above is 83.37% of a small fraction and should be ignored.

Basically it means 'strace -c' is meaningless to regular users and should be ignored.
