I did more. My version is faster.
even if your private miner is faster by a few percent or even 50% faster than djm34 release, i still using his miner instead for a simple reason... it's FREE (thank you for all the donator).
It's "free" because we donated 2.5 BTC in total
For sp miner you have to donate yourself 0.1 BTC.
It's a different approach, important thing is that devs should be paid for their work (by donation or buying private miners).
