There has to be an optimised miner here - im not getting anywhere near what I should be with 4000 cores on it. (Yes cores).
Who is mining this with a large farm and what stats are you getting?
I though I had a lot of cores going at ~100. I had problems getting more then ~100 threads mining on a single riecoind instance, so in desperation I switched to solomining on each host. I'll have to merge the wallets later, but I am getting about 500000 to 1200000 knumbers/s (per host) and from the few wallets I am monitoring I have found zero blocks.
