I disagree. Have you seen the benchmarks where they showed Python code in pypy running faster than C equivalents? Sure they were contrived, but they support the idea that theoretically any JIT runtime should be faster than ahead-of-time compilation. It makes sense to me, since the JIT runtime has more information with which to optimize the code - pypy knows what's going on with the code while it's executing, whereas the hiphop compiler only has information about the code itself. In addition, an implementation in pypy should be able to support eval, which is impossible (or perhaps extremely difficult) with hiphop.

They were far from all contrived: many were taken from bottlenecks in real Python applications. Off-hand, at least the django, genshi, and html5lib benchmarks are very much real code, and none of the three benchmarks are optimized for PyPy in any way.

  Yes, running Django in pypy gives you enormous speed boosts (I've seen it myself), but that's not what I was talking about. I was referring to the benchmarks in which they measured Python code in pypy running against pure C code (see some examples below). While I'm not familiar with the benchmarks you're referring to, I doubt anybody implemented all (or even parts) of Django, genshi or html5lib in C. http://morepypy.blogspot.com/2011/02/pypy-faster-than-c-on-carefully-crafted.html http://morepypy.blogspot.com/2011/02/pypy-faster-than-c-on-c... http://morepypy.blogspot.com/2011/08/pypy-is-faster-than-c-again-string.html http://morepypy.blogspot.com/2011/08/pypy-is-faster-than-c-a...

    See http://speed.pypy.org/ http://speed.pypy.org/ for the benchmarks I was referring to: that's the general collection of benchmarks used for PyPy (several, such as the html5lib one, imported from unladen-swallow), though obviously in specific cases comparisons are made otherwise.
