Parting shot: I also used time(1):
before:
tiotest -t 512 -f 32 -b 4096 -d . 14337.17s user 3931.52s system 301% cpu 1:40:51.08 total
after:
tiotest -t 512 -f 32 -b 4096 -d . 10985.23s user 3524.50s system 266% cpu 1:30:48.80 total
i.e. it sped up the run by 10 minutes, or 10% of the total execution time.
