# Description:
|
|
# Trigger fio runs using the random_writes job file. The number of runs and
|
|
# data collected is determined by the PERF_* variables. See do_fio_run for
|
|
# details about these variables.
|
|
#
|
|
# Prior to each fio run the dataset is recreated, and fio writes new files
|
|
# into an otherwise empty pool.
|
|
#
|
|
# Thread/Concurrency settings:
|
|
# PERF_NTHREADS defines the number of files created in the test filesystem,
|
|
# as well as the number of threads that will simultaneously drive IO to
|
|
# those files. The settings chosen are from measurements in the
|
|
# PerfAutoESX/ZFSPerfESX Environments, selected at concurrency levels that
|
|
# are at peak throughput but lowest latency. Higher concurrency introduces
|
|
# queue time latency and would reduce the impact of code-induced performance
|
|
# regressions.
