Correction, two of the loops were going backwards (mixin and hand
unrolled). Fixed this but the conclusion remains the same.

I managed to get some free time to look at this and it would appear that
static foreach is slower than hand unrolling a loop. Fortunately there
are no detectable differences between hand unrolling a loop and building
the body of the loop in a compile time string and using a mixin. Results
