There's some console command stat or stats if I recall correctly that shows where the frame time goes. Also probably Unreal Insights can show what code takes the most time

If you have a lot of code in Blueprints and it takes too much frame time you can consider using blueprint nativization, it has its own limits, basically you can't use some BP features with it (mainly some new features that are not yet supported for nativization). We used it on one mobile project and it was a big win for performance. But for desktop it may be not that big difference I guess.

it produces a very ugly code but i thought about it to convert all blueprints before final shipping compilation. don't know if there is any bad behaviour in it or not

If you know that you will use it it's better to start early, because you may use some code that can't be nativized. As for readability, this generated code doesn't meant to be read (well, sometimes when hitting some difficult to trace bug that reproduces only with nativization you may have to do that, but that's super rare).

It fails a build with some errors, I don't remember exactly at what step but it's not always clear that the problem is in nativization. So if it's being enabled at late steps of the development it can be a pain to investigate why it doesn't work.

It would be a lot of work and digging into the engine to support it, so I guess it's unlikely

If it's easier to you to work with C++ only you can do it and it's completely fine. Exceptions are UI code, AnimBlueprint code, and probably the code related to high-level AI. These are very tedious to do in C++. I usually create a class in C++ and then a class in Blueprints inherited from it to bind data and tweak values.
