Yes, the reason why that would be interesting is because it allows us to put the performance gain with master+"performance" into perspective. We could see how much of a change we get. Does the CPU governor also affect the result when you benchmark with real disks instead of ramdisk? I can see how the governor would affect ramdisk, but would expect real disk I/O to be impacted much less.
