I need a review of this change which is to help the AES/GCM intrinsic activate on large data sizes. It's not the ideal resolution, which splits up the crypto operation in chucks, but I significantly improves performance for larger data sizes. Additionally there is an optimization to not allocated and use an unnecessary buffer in the init()-doFinal() case that helped performance with large data sizes. The final result was a 1MB file is encrypted at 2GB/sec vs 250MB/sec.
This change is not meant to fix all possible performance bottlenecks. http://cr.openjdk.java.net/~ascarpino/8201633/webrev/ Tony
