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. Regards, -- Nicolas George
