But that is just for Django templates. What about the other parts of Django? <br><br><br>1) For URL routing Django uses the re module,
which is a C extension. Would JIT work with that? <br><br><br>2) Other parts such as DB driver also contains C code, again would that work with JIT? I suppose I could use a pure Python driver, but would a JIT'd pure Python driver be much slower than a native driver? <br><br><br>In general are there any rules of thumbs regarding PyPy and C extensions - what works, what doesn't? <br><br><br>Thanks. <br>_______________________________________________ <br>pypy-dev mailing list <br><a ymailto="mailto:pypy-dev@python.org" href="mailto:pypy-dev@python.org">pypy-dev@python.org</a> <br><a href="http://mail.python.org/mailman/listinfo/pypy-dev" target="_blank">http://mail.python.org/mailman/listinfo/pypy-dev</a> <br><br><br></div></div></div></body></html>
