I'm beginning to think the same thing but it's more than that, when you first run it you get really nice looking numbers, then after a couple of hours, what you say sets in.
Here is the comparison of DSTM vs BMiner.
First line is DSTM that had been running for a few days
Next line is Bminer after 3 hours. I saw grossly deviating current hash as well.
This was a GTX 950 that I just happened to have, but the two sets of number are on the same computer with the same hardware, etc.
0H/s 155.9H/s
80H/s 147.9H/s
As a final test, I'm going to leave it running in -nofee mode while I do some other work on a different miner
Can you run your numbers again with devfee turned on?
The miner will disable a number of optimizations if you disable devfee.
Maybe I mis spoke - those numbers above are *with devfee turned ON* and are what FlyPool is reporting, not the miner software. Probably the biggest problem is that the radically changing instant hash rate, I see it cycle up and down by huge margins like over 100h/s in this case and this is just a small GPU.
I'm running in -nofee mode right now just to see what happens
The mining pool is estimating your hashrate based on the number of shares that the miner has submitted.
Given that you have only one GPU, it will take a while to stabilize. I would suggest running both miners for at least 24 hours to get the results.
