Jelle Zijlstra <jelle.zijls...@gmail.com> added the comment: I found that replacing __call__ on the NewType class with an identity function written in C makes things faster instead:
In [54]: %timeit ntc2(1) 79 ns ± 0.37 ns per loop (mean ± std. dev. of 7 runs, 10000000 loops each) In [55]: %timeit ntc(1) 126 ns ± 0.315 ns per loop (mean ± std. dev. of 7 runs, 10000000 loops each) In [56]: %timeit nt(1) 103 ns ± 4.23 ns per loop (mean ± std. dev. of 7 runs, 10000000 loops each) Here ntc2 has __call__ implemented in C, ntc is the previous class-based version and nt is the current function-based version. So perhaps we could just stick a private `._idfunc` in some C-implemented module (functools? types?) and use it as the __call__ for our NewType class. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue44353> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
