I suggest to use some real-world workload - you can use something that you already use to verify the performance of RHEL. The problem with fio is that it generates I/O at random locations, so there is no bio merging possible, so it will show just the IOPS value of the underlying storage device.
OK. That's the information was as looking for. So we'll be sure to run some real world workloads that hit the bio merging code path.
