So… May be solve:
“Но по факту помогло именно -s, а не -E. И в readme по cgminer написано:
–scan-time|-s Upper bound on time spent scanning current work, in seconds (default: 60)
–expiry|-E Upper bound on how many seconds after getting work we consider a share from it stale (default: 120)”

Set “-s 5” and R=1/6*A.
Set “-s 5 -E 20” and R=1/10*A.

О! F@##! Idiot!! =)

Stratum: stratum+tcp://featherpool.com:9998
Longpoll: http://featherpool.com:9999 - i’m use…

If set Stratum R=(1-5)%*A.

Pool fails. Returns the hash…

[i]“News

There anyone there??.. >:(

Pool: https://featherpool.com
Miner: cgminer.

I see a lot of lines with & .
What does this mean? How to fix it?
When minied LTС I have not seen such lines…

So it’s OK, or a problem?
