ccminer slowing down after few minutes? (assist if possible, please...)

[seoguru]

Hi, I am new to mining and I am using ccminer with my GTX 1080. My system is an i7 7700k w/ 32 GB of DDR4 and what's happening is that the first 1-2 minutes of running ccminer i get about 100-200 "accepted" messages but the then it starts taking several minutes for the next 100-200 "accepted" messages. E.g., I reach 200 "accepted" super fast and then it goes super slow so after several hours I am around 700/700 "accepted" is this normal? How do i reach 200 within minutes and then it goes MUCH slower after initial run? Not sure if normal or perhaps I need to adjust something for something more consistent etc? Any assistance appreciated!

Yes, this is normal - it is the pool ratcheting up the difficulty for your particular IP address. Higher difficulty shares earn more per block (you can think of them as bigger pie slices, where the block is the pie) so nothing to worry about.

Thanks for the reply, would this also mean that the longer my IP or ccminer is running the bigger piece(s) of the pie I will receive or everything from A to Z is randomized? I hope I made sense; thanks!

Ideally, the pool settles on a difficulty level for your miner's hashrate capability that results in a share every minute; in practice, the difficulty level tends to oscillate over quite a wide range. The behavior is eerily similar to an instability phenomenon in feedback loops called the Right Half Plane Zero, but that's veering off into the engineering weeds.

Suffice it to say that most (honest) pools will give you close to the expected payout if you stick with them for more than a few hours at a stretch; 24 hours or more per coin usually gets you a fair result.

EDIT - but to answer your specific question, yes, the longer you mine a particular coin at a particular pool the closer your actual payout will come to the predicted based on your miner's reported hashrate vs. the average difficulty over that time period.
