Did you intentionally use heap byte buffers, or should the test use direct
buffers?
That is a good discussion point as there is a matrix of heap vs. direct,
blocking vs. non-blocking, scatter/gather, ... that could be added to
create more comprehensive micros. I don't have a strong opinion on this
but your suggestion for heap vs. direct would be useful to have as it
would help track of the overhead of copying in or out of temporary
direct buffers (this overhead has been reduced significantly in recent
releases but should still be observable in micros that don't do anything
but send/receive or read/write).
