Yes, should be. Looks like the average regression is around 4-7ns, or 12-21 cycles on a typical 3GHz machine.

UInt16 looks to be an outlier in that it doesn't match the numbers for Int16, even though they are effectively doing the same thing. I'm suspecting this one is more noise and will normalize to be the same as Int16 and the other smaller types.

Int64/UInt64 are worse than what we saw locally. This might be machine specific, but its probably worth us digging into a bit and seeing if there's some specific tweak we can do. Are there any known codegen issues for 64-bit integers on Mono?

EDITED: The "trait" accessors do indeed get inlined. I was testing Debug before.

@kotlarmilos Did these benchmarks regress on arm64, too?

It seems that they regressed on arm64 as well, you can check them at https://pvscmdupload.blob.core.windows.net/reports/allTestHistory/refs/heads/main_arm64_ubuntu%2020.04_LLVM%3Dfalse_MonoAOT%3Dtrue_MonoInterpreter%3Dfalse_RunKind%3Dmicro_mono/AllTestindex.html.

No longer regressed on AOT-llvm x64 scenario
