Mining with NVIDIA Quadro M4000 / 8 GB

Hello,

yesterday i started eth mining with a workstation, which has a Quadro M4000 with 8 GM inside.
As a pool I use coinotron, but I do not understand why the Nvidia Quadro M4000 with 8 GB of RAM is so slow?

According to coinotron worker Monitor 1,2 MH

Can someone give me some tips what I do wrong?

The command with which I start the mining start is:

mining_proxy.exe -o coinotron.com -p 3344
geth --rpc console
ethminer --form-recheck 200 -G -M -F http://127.0.0.1:833...ername:password
