Our best performance currently is in C++ code and LLVM is something we are considering using to compute expressions, such as predicates and select clause items. This is most likely to be way faster than what we can currently do in Java. What I would like to know if LLVM can optimize all the way to AVX512?

We also need to experiment with hugepages. The beauty is that if read and write are separated - there is no issue with writes. They can still use 4k pages!
