I thought I would try factoring some small exponents (under

Otherwise ECM on small exponents, or trial factoring on those

Big SSE2 FFTs now take the L2 cache size into account. P4 Celeron (128KB
L2 cache) is faster for FFTs between 512K and 2M. P4 Northwood (512KB
L2 cache) is faster for FFTs larger than 1M.
Great! I specifically remember asking about L2 cache effects months ago, and
being told
