Looking to maximize performance when using ethereum-ethash

[Ramki...@hotmail.com]

I tried using bench on AWS servers (the most expensive Compute and Memory Optimized ones) on https://github.com/hackmod/ethereum-ethash/blob/master/ethash_test.go#L88 but for each server (from 2 cores all the way to 64 cores) they all give similar numbers 9-12 seconds.

cpu: Intel(R) Xeon(R) Platinum 8375C CPU @ 2.90GHz

Is there a way to optimize this or is there a better package for this that I'm not aware of?
