Iozone is fine and I think you give me a good reason to turn my eyes
into it again . I decided not to check it due to the fact that is a
micro bench and sometimes users want numbers of something they can
feel ( how fast can I de compres , how many transactions per second
can my DB manage , how fast can I build my product )

I was answering in Greg mail , that it might be good to came with a
BKM of tests for the kernel , a list of linked test ( if you move this
you will affect that , please test before commit ) , it might be just
an initial idea but sure for industry might be something helpful

Feedback more than welcome
