So I have tried several different pools and no matter what I do I end up getting roughly 5% rejected shares due to expired job.
2 KH - 5% = 1.9 KH
Sort of evens the mining software playing field if you look at it that way.
Has anyone solved the rejected shares problem yet?
Is there a fix in the works?
The problem is system immanent and the outdated shares correlate with the job time which should be 120 seconds for Monero.
As the high hashrate is achieved by the high parallel processing of the hashes, the Vega computes 4000 Hashes at once, so for the outdate shares:
To calculate 4000 hashes with 2000 Hashes per second it takes about 2 seconds for the flight to get the results.
2 seconds round trip time divided by 120 seconds average job time gives an maximum dead time of 1,7%. If the job time decreases the rate will increase but will also decrease when job time goes up.
I see about 2% outdated shares after running 24 hours, which is perfect in line with the prediction.
One idea is to faster cancel the current job if a new job is incoming could have the outdated percentage to less then 1%. Currently evaluating if it has an benefit... maybe in an upcoming version....
