> For big monoliths (like ours at IG), the server start-up can take more than 10sec, which is already super high for a "edit -> refresh" workflow. Introducing a Cython like compilation step is really a major drawback for every single developer.

Then skip it for your dev builds.

Can you elaborate on what you mean by "skip" Cython compilation on dev builds? How would you then test changes to Cython code?

So we weren’t talking about Cython specifically, but something Cython-like, i.e., we’re not talking about Cython’s special syntax but rather ordinary Python. This is important because it means that dev builds execute against CPython directly (i.e., your code begins executing immediately) while production builds use our hypothetical AOT compiler.
