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...
