# Description:
|
|
# Trigger fio runs using the random_readwrite_fixed job file. The number of runs and
|
|
# data collected is determined by the PERF_* variables. See do_fio_run for
|
|
# details about these variables.
|
|
#
|
|
# The files to read and write from are created prior to the first fio run,
|
|
# and used for all fio runs. The ARC is cleared with `zinject -a` prior to
|
|
# each run so reads will go to disk.
