We hear that from time to time on the Cython mailing list. Here's a recent
example of a user who reported an 80 times speed-up before we helped in
getting the code straight, which brought another factor of 20.
Speed-ups in the order of several hundred times are not uncommon for
computing intensive tasks and large data sets when you move from Python to
Cython, as it generates very optimised C code.
