I've taken care to look for ways that I might have been using Numpy itself inefficiently (and I did find a problem once: fixing it tripled my execution speed).  But I would like to think that Numpy itself, since it is already a C extension, should be optimal.

Ahh, yeah, that's gonna take a while. Your minimum processing time is
likely to remain fairly high. There won't be any stupidly easy
improvements to make (like one of my favorite examples from
databasing: an overnight job became a three-second run, just by making
proper use of a Btrieve file's index).
