19# Description:
20# Trigger fio runs using the random_readwrite job file. The number of runs and
21# data collected is determined by the PERF_* variables. See do_fio_run for
22# details about these variables.
23#
24# The files to read and write from are created prior to the first fio run,
25# and used for all fio runs. The ARC is cleared with `zinject -a` prior to
26# each run so reads will go to disk.
27#
28# Thread/Concurrency settings:
29#    PERF_NTHREADS defines the number of files created in the test filesystem,
30#    as well as the number of threads that will simultaneously drive IO to
31#    those files.  The settings chosen are from measurements in the
32#    PerfAutoESX/ZFSPerfESX Environments, selected at concurrency levels that
33#    are at peak throughput but lowest latency.  Higher concurrency introduces
34#    queue time latency and would reduce the impact of code-induced performance
35#    regressions.
