It'd be interesting to see performance numbers for `putPair` vs `ByteArrayLittleEndian.setInt` in isolation on x86. I.e. before and after this PR. When I've tested a similar thing for #15591 I saw a slight win on a two-byte pair (that might be due improved inlining decisions) but regressions on 4-byte or larger writes. ------------- PR Comment: https://git.openjdk.org/jdk/pull/15652#issuecomment-1713969279
