execution time on RPI.

I am trying to measure the execution time of a function on RPI model B.
I used the "Trace::timestamp" function to calculate it. In the same time, I
used the elapsed_ms() function to compare with it.
as I understood, the "Trace::timestamp" function gives the performance
counter. Dose the elapsed_ms function provide the execution time of the
method in milliseconds?
During the measurements, I got some related numbers in somehow. For an
example, the average of elapsed_ms() was 2,18 and the average of
performance counter is 24825,02
How could I convert the delta of the performance counter to milliseconds? I
guess I need to divide by the CPU_cycle.
If yes, does the cpu_cycle specified or modified by the Genode? How can I
get this value?
