> If I do, I won't go Java, I will choose something that is built for performance. Python is good enough for 99% of my performances need. The last 1%, jumping to java is not a big difference, I'll use rust or go.
So given that, I am curious where are those GUI alternatives with the required perfomance in Go and Rust.
- you need a GUI
- you need perf beyond what Python is capable and you identified it clearly in advance
- you can't use numpy / multiprocessing / cython, pypy or they won't give you the perf you need
- you can't find a main hotpath you can optimize with a 5 lines c or rust extension and write 99.99% of your app in python. Or you don't want to bother.
If you ever find yourself in this very use case, then yes, use Java.
But I never found myself in this very precise use case.
Please.... That's literally the worst option for python on this planet. For all "just do multiprocessing" the tooling is horrible garbage. Then we get to Twisted and Gunicorn the Spring Framework of Python world.
