Benchmark scores did not show a significant pattern. I did not measure CPU stats though. But I still think a dynamically calculated shift makes sense, and I hesitate to change this code at this point. I therefore would like to move this question to followup RFEs if necessary. ------------- PR Review Comment: https://git.openjdk.org/jdk/pull/20677#discussion_r1810775878
