Nethash 2.10 GH/sec

How is it possible with cryptonight coin ?
Someone could elaborate for me?

Thanks in advance.
its not cryptonight
its a cryptonote coin but the algo used is wild keccak
Ok thanks I know but as far as I know wild keccak is still not GPU-mineable.
And people report mining with cpuminer-multi with 200h/s hashrate.
So what does make the number of 2 Gigahash/s then?
That's what I don't understand.
Thanks again.
