Subject: [RFC v1 0/1] nvme testsuite runtime optimization

While testing the fc transport I got a bit tired of wait for the I/O jobs to
finish. Thus here some runtime optimization.

With a small/slow VM I got following values:

with 'optimizations'
  loop:
    real    4m43.981s
    user    0m17.754s
    sys     2m6.249s

  rdma:
    real    2m35.160s
    user    0m6.264s
    sys     0m56.230s

  tcp:
    real    2m30.391s
    user    0m5.770s
    sys     0m46.007s

  fc:
    real    2m19.738s
    user    0m6.012s
    sys     0m42.201s

base:
  loop:
    real    7m35.061s
    user    0m23.493s
    sys     2m54.866s

  rdma:
    real    8m29.347s
    user    0m13.078s
    sys     1m53.158s

  tcp:
    real    8m11.357s
    user    0m13.033s
    sys     2m43.156s

  fc:
    real    5m46.615s
    user    0m12.819s
    sys     1m46.338s
