time a.out
106.130u 0.000s 1:46.28 99.8% 0+0k 0+0io 83pf+0w
As per my understanding of the man
page:
- the first value is the time since the code execution started and ended,
- the second values is the time spent in usermode
- the third one being in kernel mode
Is the 99.8% indicating time spent in kernel mode?
Also, what does this indicate?
0+0k 0+0io 83pf+0w .
The program definitely takes more than a minute to execute – then why is the first value so small?
