We've run some tests with PyPy on Read the Docs itself but not for ads. For Sphinx documentation builds, builds took around ~50% of the time. It was especially pronounced on builds with large numbers of doc files (hundreds) and therefore complicated side navigation.

I get that python is under 30% of your profiled time, but just wondering if you tried PyPy?

Right, Sphinx itself is not JIT friendly, but I thing django should be faster
