OK, now you may enable OpenMP (uncomment the OMPFLAGS line in the
Makefile as the README suggests) for a speed like:
Will run 8 OpenMP threads
Benchmarking: bitcoin, bitcoin (iterative SHA-256 + AES-256) [32/64]... (8xOMP) DONE
Raw: 48.0 c/s real, 6.0 c/s virtual
This is on AMD FX-8120.
Alternatively, you may run with "--fork=8" (or whatever number is right
for your CPU). For either approach to make sense, you need to export
multiple logical CPUs into your VM.
