Thanks for the update. The optimizations to Lyra2v2 are much appreciated.  I have small suggest concerning the dev fee mechanism, however. Would you consider hiding the accepted results and hash rate messages when the miner is working on the dev pool?  The issue is that if you are trying to do any calculations based on those numbers, the results from the dev pool work can skew the averages. Since the dev pool work doesn't correspond to the user's work, it would be preferable to hide performance messages related to the dev pool. Thanks for considering my suggestion.
