Do I/O requests in the Linux kernel get "backlogged" when they all hit the
same device? Or would you get better throughput (or less latency) by
spreading the load across multiple devices?
(A long-running synchronous IO request seems it would block everything
behind it, whereas objects in tablespaces on different devices could still
be queried.)
