No and I do not intent to do, as it was ja a code simplification I have seen, not an engineering target actively developed to reach max performance. Did you measure a performance drawback of the latest code? Maybe Compiler optimization is less productive in that particular case, due to the constraints mentioned? ------------- PR Comment: https://git.openjdk.org/jdk/pull/21371#issuecomment-2407903343
