[20:40:31] <justJanne> So, I benchmarked read and write for arrays, int buffers, byte buffers, java’s own, lwjgl stack ones, and memoryutil ones. And the result is: Even with JDK9, only the array accesses can be vectorized with AVX2, the rest can not. That said, the performance over a few billion additions of 1000-ary vectors is https://hastebin.com/raw/iwoqadiwol per million additions
[20:41:22] <justJanne> results are pretty obvious, unaligned memory access is slow unless it’s to a DirectByteBuffer, and vectorization is a performance benefit of a factor of 4 for vector addition
