Hello list,
i still don't understand why the speed of the rados bench depends so
heavily on the threads.
Right now i get around 100MB/s per thread. So 1 thread is 100MB/s, 4
Threads 400MB/s and 16 threads results an about 1100MB/s.
So 1100MB/s is great but i still don't get why 1 thread gets "only" 100MB/s.
