Hello,
I did some benchmark on psycopg3 and got a pretty grim picture of how
slow a pure Python module is compared to something similar written in
C...
As per original plan I added an optional C implementation
(specifically, written in Cython, to help with boilerplate/refcount)
and the result is a sweet 20x speed-up.
If you are interested I have a write-up of the profiling/optimization
process here: https://www.varrazzo.com/blog/2020/05/19/a-trip-into-optimisation/
Cheers!
