Before inventing a hyper tool, we might consider to provide 3-5 example
szenarios for common hardware configurations. This consumes less time
and be discussed and defined in a couple of days. This is of course not
the correct option for a brandnew 20 spindle Sata 10.000 Raid 10 system
but these are probably not the target for default configurations.

If we carefully document these szenario they would we a great help for
people having some hardware "between" the szenarios.
