Line 2,180:
This approach gave slightly over a 2x speedup for <tt>taskorder 10</tt>, from a 2 element cache, with an approximately 50% increased memory footprint. (Remember, of course, that benchmarks and benchmark ratios have dependencies on computer architecture and language implementation, and the host environment.)
A further roughly 8x speedup can be obtained here, by using the fftw addon.
<lang J>NB. install'math/fftw'
