More gain than I expected. Have you tried running a benchmark that "times all FFT implementations"?
I am very curious why the default implementation of 300K FFT is so poor on your machine.

I am now working on M72000 - M75000 to B1=1e9 (B1=3e9 if no known factors).

I've finished M75000 - M81000 with similar bounds finding 3 or 4 new factors in each range of 1000.
