no APC, with APC, and with APC and apc.stat=0. The benchmark in question compared require_once to include with full paths to a single file. In the best case, I got a 12% performance difference between include with full paths and apc.stat=0 and a single file.
12% sounds more realistic than 45%, definitely. Now what exactly the application you benchmarked did besides includes? Was it a real-life app? Which one?
What is particularly irksome about this whole nightmare is the combination of "prove it you little peon" attitude and the fact that it
It has nothing to do with "little peon". You argue that we need some language-level change to improve performance (and it is the only reason to add it). It is suspected that this language change has very high abuse potential, so we need to be sure this performance improvement is real and worth the troubles that this feature brings. Otherwise even considering it is pointless - if we have no real performance improvement on real applications, what worth it? I still think namespace syntax is not the right place to improve performance, but if I have real-life data it might be an argument for it.
.phpt tests. If the decision is to ignore input, I would really rather
Please stop it. If your single proposal is not accepted, it's not "decision to ignore input". There are a lot of proposals to PHP improvement, some of them get accepted, some of them get rejected. Anybody who is interested in developing PHP and proposes anything with any frequency is bound to have his share of proposals rejected, and inevitably he would feel hurt - if he didn't think it's an excellent proposal, he wouldn't propose it. You can claim that some of them are rejected mistakenly, and it's a valid difference of opinion. But claim that your input was ignored, after extensive discussion and multiple verbose explanations of the reasons to you is plain false.
that say: I've already proven there's a performance difference, the ball is in *your* court to prove (with benchmark) that I am wrong.
Proving the negative is impossible. You can't prove there's no performance improvement on some application under some condition - doing this would require one to convert all existing applications to single file and test them in all possible environments. However, proving real life application difference would require only one application being tested.
