Hi everybody,
There are already JMH crypto micros in the open corpus (a maven project):
http://hg.openjdk.java.net/code-tools/jmh-jdk-microbenchmarks/file/fc4783360f58/src/main/java/org/openjdk/bench/javax/crypto
that should be able to measure the benefit of this webrev against the
existing intrinsics.
Regards,
Eric

I'd like to contribute an optimization for GHASH Algorithm using AVX
Instructions. I have tested this optimization on SKX x86_64 platform
and it shows ~20-30% performance improvement for larger message sizes
(for example 8k).
Performance improvement against what? The pure Java implementation? I
find this a bit surprising. I would have expected a much larger
performance improvement from the use of CLMUL instructions.
Thanks,
Florian
