I don't see big benefits to have it in jdk 9 - no numbers for normal applications or big benchmarks. Only numbers for special microbenchmark was shown.

And I am concern about possible regressions so later in jdk 9 cycle.

I would prefer to move it to jdk 10. Unless you think it can give huge benefit to customers as we had with crypto intrinsics.

thanks,
Vladimir
