Given that PyQt uses SIP which uses the CPython C-API which isn't part 
of the Python language as far as I know the options are fairly limited.  
Though, my understanding is that PyPy has made efforts to support some 
amount of the C-API for numpy and the like.  Anyways, you could 
implement your performance bottlenecks in C++ and wrap them with SIP and 
then do the rest in Python.

Well, I suppose I actually ought to mention Nuitka.  I've never used it 
but I know a few people have used it with PyQt5 and that in general 
Nuitka claims to be faster than CPython.  It's a compiler though not an 
interpreter, or so it says...  anyways, I don't know much about it but 
maybe you get lucky and it's useful.

Cheers,
