My understanding is (I'm definitely not a Mahematica guru) that Mathematica
automatically does the biggest thing that can be done to speed up
NIntegrate-- when you run NIntegrate, Mathematica automatically compiles the
function to be integrated so that it will run as fast as possible. If there
are any other tricks for making NIntegrate run faster, I would also like to
know what they are.
By the way, if you have not yet upgraded, I have found that Mathematica 5.1
performs NIntegrate at least three times faster than Mathematica 4.1 did on
the functions that I have been integrating, which involve double integrals
of fairly large functions.
