Rrr, email made the histograms look funky (tabs vs. spaces...)
The count is what's important anyways...
Just adding that I used an Intel P3500 nvme device.
We can see that most of the time our latency is pretty good (<1ns) but with
huge tail latencies (some 8-15 ns and even one in 32-63 ns).
Obviously is micro-seconds and not nano-seconds (I wish...)
