People skilled in optimization know to profile the code and find what is
slowing real, actual applications down before attempting to profile
anything. You can't imagine how uninterested any FreeBSD developer is
in optimizing getuid() so it will out-perform Linux on some completely
braindead benchmark. Show me an application that is getuid()
performance bound and I'll show you an application that is so poorly
written as to be meaningless.
You obviously feel passionate about this issue. Why don't you pursue it
yourself? Are you looking for a few good programmers to join you, or
perhaps someone to tutor you? If so, say it up front, and I'll just
bet somebody will step forward to help out.
