I'm really looking forward to when SIMD support is released in later versions of Java. If anyone here follows handmade hero (by Casey), he explained SIMD in some of his videos when implementing the software renderer. The speedup from regular code to SIMD is very impressive. You essentially get speedup of 2x-3x or even more for free.
The downside is it makes the code much harder to read, so I think it should be applied only in very small sections of the code.
