Hi

I'm very new to this thing of mining, so sorry for the noob quesions.

I've a Strix 1080 Ti that was bougth to play games, but as my time to play is scarce, I've started to mining some Zcash

I'm running Ethos using the dtsm miner to suprnova, and getting the follow performance:

Sol/s: 650
Sol/w: 4.1
Avg: 653
Sh: 7.2

Is this a decent performance for my VGA?

Another doubt that I have is about Shares.

I think I've a good Sol/s but the Shares is too low(7.2).
Is there a way to improve this performance?
Or I'm wrong and 7.2 is a good number?

Thanks in advance
(Sorry for my bad english)
