L128X128MixRandom shows 8% improvement, L128x256MixRandom shows 6% improvement and L128X1024MixRandom shows 14% improvement. (Another micro workload shows 10% improvement for both L128X128MixRandom and L128x256MixRandom while L128X1024MixRandom shows 25% improvement in performance.) @JimLaskey Could you please review this PR which optimizes three of the Pseudo-Random Number Generators you implemented in https://bugs.openjdk.java.net/browse/JDK-8248862 ? ------------- PR: https://git.openjdk.java.net/jdk/pull/6206
