Time always equal 0, outside hard I\O doesn't affect on time. But tmp file is creating. default

As you see ioping warns about unreliable results: use writes (add -W, that's safe for directories). Seems like windows have no non-cached reads, at least I haven't found any.

Do you have any suggestion to measure latency on Windows?
