Yes - but I was referring to the performance of the native call -- not that of the allocation per se (e.g. `CallOverheadByValue`). If I'm not mistaken the numbers of that benchmark all refer to new code (well, except when we pass by pointer, in which case there's no allocation -- both before and after this PR). E.g. it would be useful to also see how the by-value call has improved before/after this PR, in addition to looking at the difference between byValue/byRef in this PR. ------------- PR Comment: https://git.openjdk.org/jdk/pull/24829#issuecomment-2847747932
