Misha Dmitriev commented on OOZIE-3250:
---------------------------------------
The last patch looks good to me. Thank you for your efforts, [~andras.piros]
It's great that you tested performance of this stuff. I realize that the
performance measurement code is fragile so it doesn't make sense to keep it as
a test that gets re-run regularly. But I think it would make sense to at least
mention your performance numbers in the javadoc of the ByteArrayUtils class, so
that in the future people don't have doubts about it.
