In general, mixing synchronous and asynchronous I/O typically brings you the worst in both worlds.

This has been a nightmare in C# which pioneered async/await - a lot of developers are struggling with footguns from mixing sync and async code.

Ryan Dhal said that he picked JavaScript for Node because he was afraid of this and wanted a language without synchronous APIs already built in.

I think Python 3.5+ async/await is fantastic don't get me wrong - but if you want to mix and match I'd recommend getting a second server that runs the synchronous framework and then communicating over network (REST HTTP for example) between the completely asynchronous server and the one running the thread pool.

The big difference is that C# supports both multithreading and parallelism out of the box. Python has multithreading but with a GIL, nodejs has none of the 2.
