It's incredible that there's actually this much room to improve. How does this compare to GPU implementations?
Also it looks like the optimization is related to running operations on a compressed representation, for the 10x vs 100x speedup, is there a tradeoff between speed and accuracy, or is that extra degree of magnitude just from bringing SIMD into the picture?
