Is Nexus still profitable to mine with CPU? How do we know the mining speed? I only have Siv/s 0.001... It doesn't seems to work well to mine on the nxscpuming pool. But the mining program doesn't produce any errors compare to other pools where it crash.
I dont know how profitable it is but 0.001 siv/s is very low. I have 3.6 Siv/s using on each of my two instances with a total of 1500 WPS. Please check you miner.conf file. I use the following values:
"sieve_threads": 5,
"ptest_threads": 8,
"timeout": 30,
"bit_array_size": 3145728,
"prime_limit": 71378571,
"n_prime_limit": 3000000,
"primorial_end_prime": 12
They are most probably not optimized but might help you.
