Description
Curious if you've thought about whether it's beneficial to use the jdk.incubator.vector library. I noticed your posted benchmark for xxHash (not sure which variant) is an impressive 9.5 GB/s, which is just under the native version's XXH32 speed of 9.7 GB/s. Can we get it to "RAM speeds" that the native version's XXH3 (with SSE2) advertises by using explicit vectorization?
Amazing work here in this library btw!
