Hi @eme64 @jatin-bhateja, I'v created a PR https://github.com/openjdk/jdk/pull/25539 to fix this issue. With this change, the performance regression can be fixed as well. Could you please take a look at that change and help to run the test on different X86 machines? Thanks a lot! ------------- PR Comment: https://git.openjdk.org/jdk/pull/25138#issuecomment-2921574716
