In the second part of my message I referred to top/htop output which clearly
shows that IO wait is treated like it is _real_ CPU usage but you just ignored
it and now

you sound like "even though most sane people trust their eyes, in Linux you
should not trust your eyes, everything is so complicated we don't even have
utilities which can show real CPU usage".

And until we have such utilities and metrics which allow to instantly _see_ and
_not_ deduct real CPU usage people _will_ keep on bitching that Linux is broken
with my motherboard/chipset/HDD Linux because IO wait OR Linux gobbles down my
precious CPU cycles.

Just run Windows and see how easier it's to _see_ whether system is busy or
occupied. In Linux everything is such a way no layman (except kernel
developers) can really understand.

If you insist that everything is just fine and works correctly as intended I
have to resign and keep silent from now on and realize that Linux is only meant
for über geeks.
