One thing that concerns me is the warning to only use a filesystem created in a certin way for the benchmark, don't use a tar of an ext2/3 filesystem as that will kill performance.
they say taht there will be a tool to fix this in 4.1, but this makes me treat the benchmark as a 'best possible' test case and expect the real-world performance to be considerably worse (how much worse who knows, I haven't seen anyone try to do worst-case performance tests on it)
