I'm assuming you mean what is the CPU load of the MN ? Rather than what computations are going on that actually account for the CPU load ? If the former, well here's mine, since I set it up a few days back.. Big spike, is the installation, compiling etc.. After that, well you can see for yourself.. Hovering around 6% or so..

If you meant the latter, then don't ask me
