A patch has two part. First is separating outputs to which I raised no
objection.
Second part is adding benchmark for memcpy. It is based on scientificaly
unsound methods and results from it will not be statisticaly
significant.
I will accept that patch without memcpy benchmark or with proper
benchmark.
