Hi,
To get more accurate benchmarks we need precise timing.
Could you provide a version for arm?
After bit of googling I found arm performance counters here.
http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.faqs/ka4237.html
It should be possible to in init setup cycle performance counter and
then read timing from it.
I am not expert at arm so I would leave this to somebody with more
experience.
