What are you trying to measure, exactly, and why?  The answer depends on
the details of the question.

However, my first go-to solution would see if 'perf' can cough up the
numbers you need.  It's able to slurp out all sorts of timing data from
the kernel (though some data and trace points require CONFIG_* variables
to be set in the kernel build).
