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.
24 # Prior to each fio run the dataset is recreated, and fio writes new files
25 # into an otherwise empty pool.
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
