Anyone else been keeping an eye on testnet?

Difficulty is rising pretty fast, which means some serious mining from a very small base is happening.

I see a difficulty below 17. Thats <100k pps total.

Let me show you how to optimize the miner:


Thanks to riecoin my gmp is already custom compiled and tuned.  I only mentioned testnet as the diffidently was high and was increasing at a steady rate.

Interesting that you get some performance out of SIMD with the code as is.  One of the first things I did was to compile with "-ftree-vectorize -mavx2 -ftree-vectorizer-verbose=5" to see what auto-vectorising found.  It didn't find much (any?) to vectorise as most of the size of the loops aren't know at compile time (there are trick you can use however) or a non-uniform step being used.

Regards,

PS.  The fact that GCC couldn't vectorise what should be very conducive to vectorising is a good avenue to work on for speed-ups.
