Thanks Andrei and simendsjo for a quick response though.
Python's splitter, which you are measuring, isn't written in
Python. It is written in C. You're actually comparing a bit of
C code with a bit of D code.
This.
If you wrote the splitter in pure python you would see an
enormous performance gap between it and the D version.
Having said that, maybe there are even more improvements we can
make to improve speed in that part of photos, but considering
we're already on a par with some quite mature and optimised C,
there really isn't a problem.
