bottleneck and that eliminating it can lead to significant speedups. As a consequence I'm interesting in the performance tradeoffs.. bottleneck and that eliminating it can lead to significant speedups. As a consequence I'm interesting in the performance tradeoffs.. nested loops I've seen dramatic seriously dramatic speedups in this realm. I saw more improvements from this than I later..

is kinda ridiculous. You probably won't see these kinds of speedups converting i.e. matrix ops to SSE or int hacks since this is..
