Hello, There was a very interesting talk at Pycon about using Cython to speed up hotspots in Python programs:
https://www.youtube.com/watch?v=_1MSX7V28Po It got me wondering about possibly using Cython in selected places within Django. I realize since Django was first released the distribution situation was a bit more wild-west, resulting in part to Django not relying on any third party dependencies. But that situation is rapidly changing (see https://github.com/django/deps/blob/master/draft/0007-dependency-policy.rst#background-and-motivation) and with these changes could it also be a time to investigate Cython usage for select parts of Django? Several popular projects use Cython 'speedup' modules with pure-python fallbacks with great success, for example aiohttp ( https://github.com/aio-libs/aiohttp/blob/master/setup.py#L20). I did some quick and dirty profiling of the 'django.utils.html.escape' function and found that by simply including Cython as part of the build, and with no syntax changes, the function executes twice as fast. There are lots of considerations to take into account (like ensuring the Cython functions are in sync with the fallback ones), but it seems that it could make a big difference with small, self contained functions (like html.escape or html.escapejs) that are executed frequently as part of a request. Other functions that might be worth looking at include core.http.mutliparser.parse_header or utils.baseconv.BaseConverter.convert. My question is: this this something that's worth exploring, or is it outside of the realms of possibility? -- You received this message because you are subscribed to the Google Groups "Django developers (Contributions to Django itself)" group.
