I'm not sure that latency addition is quite correct. Most use cases
cases do multiple IOs at the same time, and good benchmarks tend to

I suspect the IO limitations here are a result of QEMU's storage
handling (or possibly our client layer) more than anything else — Josh
can talk about that more than I can, though!

Same results with rbd kernel driver without QEMU involved.
