After playing around a bit more, I've found that on my i5 6600 systems with DDR4-2133, a single worker delivers more throughput than two.

I suspect that may be due to the relatively small 6 MB of...

Interesting how hyperthreading gives a small boost to the single worker case for all but the largest exponents.

No drop at the larger FFT sizes as it all fits in L3 cache.
