Thank you for your tests. Looks like we need NEON optimizations to get a good hashrate. Also I'm not sure if I compiled Release or Debug.
I think I added NEON, but now it just crashes emulator. I'll continue research. If you can help, the code is still in

Thanks!
We need multi-core / thread support and AES-NI support
Check this out
https://online.tugraz.at/tug_online/voe_main2.getvolltext?pCurrPk=67985Technical University Graz (tugraz) helped develop Grøstl together Denmark Technical University.
PLlase consult the existing ARM NEON Grøstl implementations with AVX2 and AES-NI support
http://www.groestl.info/implementations.html. Everything is there already!
NEW! The first Grøstl-256 implementation using AVX2 VPGATHERQQ instructions using only 169 instructions per round can be downloaded here.
NEW! A new Grøstl-256 NEON implementation using bitslicing (48.6 cycles/byte on Cortex-A8, Hercules eCAFE) is available in eBASH.
NEW! A vperm implementation of Grøstl-256 using NEON can be downloaded from eBASH. This implementation can serve as a basis for future NEON implementations using ARMv8 AES instructions.
NEW! The first Grøstl-256 NEON implementation running at 45.8 cycles/byte (Cortex-A8, Hercules eCAFE) can be downloaded from eBASH.
NEW! Improved Lightweigth Grøstl implementations have been submitted to eBASH, resulting in an overall 3rd place in XBX.
NEW! The Grøstl-512 AVX2 implementation presented at the 3rd SHA-3 Candidate Conference with 40% less instructions (compared to AVX) can be found here.
NEW! First Grøstl-256 implementation below 10 cycles/byte on Intel Core i7-2600K with AES-NI (see below).
The numbers people are seeing now are nothing compared to what we will with an optimized miner
I believe all the "hard" work has been done
50,000 GRS BOUNTYIm getting really excited about this now!!!
