POWER8 AES vector optimizations

[munroesj52]

Your performance problems may be related to load/store and not the crypto operations.The SHA ops are all listed in the User Manual as 2 Cycles and AES as 6-7 cycles.

Make sure your compile is actually inlining the ops. For GCC use attribute((flatten)), Also you may need to unroll you looks a bit. For GCC use attribute((optimize ("unroll-loops")))

If still disappointed you can use performance tools performance simulator and PipeStat to find the bottlenecks.
