Also you might ping the pool's server, opening a Command promt and running for example:
ping zec-eu.suprnova.cc
you'll see if average is too high (above 350ms).
Regards.
350 ms is SLOOOOOOOOW.
I can ping most servers across an OCEAN in 120-180ms.
In my country within 100ms.
I agree..I was wondering where the limit would be.. I'm using Antpool @200ms ping...and Suprnova (Europe) 25ms... How much would affect mining with a "lazy" ping? How could we measure that?
