Averages over many iterations will smooth out variances, differences
due to cache warming, etc. Additionally, the performance of any API
will vary in terms of its overhead across different implementations,
but presumably these are small relative to the operation(s) that are
being measured.

Time should be measured over a number of iterations, so that
overhead of those two time stamp reads per iteration is not
significant. Maybe you are already doing that by default (with
those 10k iterations) and would hide the difference anyway (e.g.
overhead difference of 2 vs 3 cpu cycles per iteration).
In addition to (or instead of) time, performance could be measured
in CPU cycles which highlights implementation efficiency.

Different implementations may have different overheads for getting
the nanoseconds number. This overhead may accumulate when time is
read repeatedly and impact the overall value.

Using time API makes the performance test OS independent
but it makes the actual results dependent also on the time
API implementation. This could be an issue especially when
comparing crypto performances of different platforms.
How is that? A ns is a ns no matter how it's implemented.

Alex, I think after 1.6 time api will be there and
it's better to reuse for performance test.

Measures the time required to launch and get the
result
of ODP crypto operations in async and sync API
mode with
configurable payload size, crypto algorithms and
iteration
number.
Both asynchronous scheduled and polled are supported.
In scheduled mode a separate worker thread is used to
get the crypto completion events.
Output packet can be reused as the input of the next
operation or a new packet can be allocated for each
operation.
Based on a previous work :
