MinotaurX is one of the top 5 in profitability at ZergPool. As I type this, it is #2, with 3 coins being served.
Profitability is not realy the issue at this point, even if it could be sustained. The killer is yespower, when it's present it dominates
everything else. There's no point in optimizing the X16R part because it won't help the overall performance. Many of the X16R
optimizations can't be applied to this implementation anyway. There's also a unique GBT protocol change that would be difficult
to test.
I believe there are at least 2 optimized CPU miners that support minotaurx already. They likely already have any optimizations
I could add.
I'm simply not interested.
