Sapphire Nitro+ 470 4Gigs - What should my ETH hash rate be on Linux today ?

[bercy]

Hi,

I set up a mining rig with 470's last may.

Then, I kinda forgot about it, it's been running flawlessly since then.

I'm running on Linux.

What hash rate should I be getting with that setup ?

Claymore reports 19-21 MHs, am I missing out ?

Any easy fixes ?

Does hash rate diminish over time ?

Tks.
