The only thing I would add/say Oleg, is have you looked at the Hendrix
CMD specific metadata tests?  I only mention this because from what I
recall, we took advantage of every opportunity we could (within the
requirements of the project) to show performance in the best light we
could.  I'd imagine that those tests (and the corresponding Lustre code_
would have considered some of the same things you are considering.

It may be however that some of the solutions were CMD specific and not
really applicable to you, but perhaps in the least, looking at some of
those tests (i.e. mdsrate was one key test) might prevent you from
re-inventing tests.
