Hi,

Referring to http://old.scipy.org/documentation/weave/weaveperformance.html (I can't find it on the new site - weave appears to have vanished), I note that there is no date on it and neither are there any details of the versions of the libraries uses. Could anyone enlighten me as to how accurate it is, as I was planning to reference it in my dissertation writeup as an example of how Python code can be speeded up if required.

I use weave in my own projects. For computationally intensive loops that cannot be written with NumPy's vector operations (use that if you can), switching to C++ often gives you ~100 times performance improvement above the same algorithm written in Python. Don't do it if you don't need to, but for performance critical code that must be executed repeatedly in your calculations, weave is a great solution. Cheers, Curtis
