Hi there,

I decided to put 2 R606 as lottery miners on a local full node. The node (bitcoin-core 0.21.1) run on a A4-5000 from AMD with a 1To SSD/8G RAM on an alpine linux with just the node and cgminer on it. Everything seems fine on the node I get 60 to 70 peers connected and the machine run alsmost IDLE (8% on 1 cpu <1% of the 3 other CPUs).


For CGminer, I've compiled latest version from for Gekko r606 (4.1.11).

I can run around 630GH/s*2 when I run cgminer solo to the http 127.0.0.1:8332 and I notice the message from cgminer "connected without LP to ..."  (which I guess is without longPoll?), I can try different frequency etc ... I'm stuck at 630GH/s, and I get reagular "peak adjust: target frequency 525.00MHz -> 518.75MHz" message down to 435 and 600GH/s.

Now if I run the same cgminer to the stratum solo.ckpool.org solo pool server then I can get up to 900+GH/s and even close to 1TH/s by raising he frequency.

Any ideas ? Is the longpoll the issue ? is the cgminer in http the issue ? Or bitcoin-core ? Any though are welcome.

Thanks.
