I cannot entirely agree with that. If you throw enough hardware at the
problem to get “at many random things in those 100T as quickly as
possible”, then the system as a whole has good performance because the
hardware has good performance, but it would be wrong to say that the
filesystem has good performance. It is just the hardware.

These advanced filesystem have a lot of features, but as far as I know
their performance are average.
