Why do you say that?
For example I'm trying to find those parameters (direct-io, fadvise,
number of threads, libaio/mmap/sync, etc.) that give an overall "best
performance" (whatever that means) on a simulated workload.
I'm using group reporting, because I want numbers for the entire system,
not for an individual thread.
Am I using "fio" wrong or is "fio" mostly used for other kinds of
benchmarking?
