You can see the results are printed in three sections.

The first section reports how many times each function was called.

The exclusive function on-CPU times shows, amongst other results that func_a

spent around 0.22 seconds on-CPU. This times excludes time spent in

other functions.

The inclusive function on-CPU times show that func_a spent around 1.4

seconds on-CPU. This includes the time spent in other functions called.

These on-CPU times are the time the thread spent running on a CPU, from when

the subroutine began to when it completed. This does not include time

spent off-CPU time such as sleeping for I/O or waiting for scheduling.

On-CPU times are useful for showing who is causing the CPUs to be busy.

See Notes/ALLoncpu_notes.txt for more details. Also see

Notes/ALLexclusive_notes.txt and Notes/ALLinclusive_notes.txt for a

detailed explanation of exclusive vs inclusive subroutine time.
