Is the inefficiency in terms of the graphics and windows message loop code,
or in the numerical stuff itself. (Personally I question the need for
floating point for most of it and suspect it is all written in high
level languages.)

Don't forget that the data is being solved for a large number chirp rates
and that the input data is only two bits each of I and Q, so this represents
400K time samples.
