no turbo boost found.

only a powermanagement menu ... I disabled it again.

It was disabled per default, other options are "efficient" and "custom"
... so I understand it as "performant" when it is disabled.

"custom" brings several options then, I had tried the performant options
already without success.

Right now I get around 18-20 MB/s for the /dev/null test.
