Do you know how this benchmark differs from the other and why this is a separate file? Plus, the directory names of these benchmarks all have `valhalla/sandbox`. It's not clear if these are leftover benchmarks or whether these are still relevant. ------------- PR Review Comment: https://git.openjdk.org/jdk/pull/32413#discussion_r3802108377
