It is easy to calculate the number of nodes per second.
The following information was posted:
3735698 54.286 Mat07
It means that the number of nodes per second is 3735698/54.286.
I guess that the hardware is also similiar to your hardware(I rememeber that
Dieter use something similiar to your hardware).
