19# Description:
20# Trigger fio runs using the sequential_writes 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# Prior to each fio run the dataset is recreated, and fio writes new files
25# into an otherwise empty pool.
26#
27# Thread/Concurrency settings:
28#    PERF_NTHREADS defines the number of files created in the test filesystem,
29#    as well as the number of threads that will simultaneously drive IO to
30#    those files.  The settings chosen are from measurements in the
31#    PerfAutoESX/ZFSPerfESX Environments, selected at concurrency levels that
32#    are at peak throughput but lowest latency.  Higher concurrency introduces
33#    queue time latency and would reduce the impact of code-induced performance
34#    regressions.
