Performance Notes - Initiator Side
----------------------------------
* For multithreaded workloads using small block sizes changing rq_affinity
into 2 improves IOPS significantly (Linux kernel 3.1 and later; see also
commit 5757a6d76cdf6dda2a492c09b985c015e86779b1).
* For latency sensitive applications, using the noop scheduler at the initiator
side can give significantly better results than with other schedulers.
