Guys.. my GPUs are working on ethermine.org pool, I have 3% of stale shares.
Is that normal? Can I reduce the number of stale shares?
Or that is a problem with the pool? For example: the pool gives the same job for multiple users/workers?
That is normal. I have 2-5% stale.
Thanks. But.. that means 2-5% of my hashrate/GPUs are working for nothing?! That's a very huge number!
