Pyrex and Cython

[Russel Winder]

Not really on topic, but there are people on this list with experience
it would be great if I could tap:

In various little experiments using Pyrex and Cython -- which amount to
microbenchmarks -- I am finding that the same tight loop, doubles-based
algorithm coding in Pyrex is significantly slower than using Cython.
Cython is relatively close to C whilst Pyrex is significantly slower,
but a lot faster than Python.

Does this match people's experiences or do I perhaps need to investigate
whether I have poor Pyrex code whereas I seem to have reasonable Cython
code.

Thanks.
