There is no fix for the JDK 17 issues with garbage collection and disabled tiered compilation. From Java 18 on we can use the new MemoryCopy class to do bulk copies. It also supports byte swap to adjust endianness: https://github.com/openjdk/panama-foreign/pull/555 The results look promising. I have a branch using that available already, will create a new pull request to record the iterations. Still we need to investiage if for the readLongs() and readFloats() the loop is better, as the array sizes are really small and the bulk copy overhead is large. I can see t already in the benchmarks. -- This is an automated message from the Apache Git Service.
