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. 36# 37 38. $STF_SUITE/include/libtest.shlib 39. $STF_SUITE/tests/perf/perf.shlib 40 41function cleanup 42{ 43 recreate_perf_pool 44} 45 46log_onexit cleanup 47 48recreate_perf_pool 49populate_perf_filesystems 50 51# Aim to fill the pool to 50% capacity while accounting for a 3x compressratio. 52export TOTAL_SIZE=$(($(get_prop avail $PERFPOOL) * 3 / 2)) 53 54# Variables for use by fio. 55if [[ -n $PERF_REGRESSION_WEEKLY ]]; then 56 export PERF_RUNTIME=${PERF_RUNTIME:-$PERF_RUNTIME_WEEKLY} 57 export PERF_RUNTYPE=${PERF_RUNTYPE:-'weekly'} 58 export PERF_NTHREADS=${PERF_NTHREADS:-'4 8 16 64'} 59 export PERF_NTHREADS_PER_FS=${PERF_NTHREADS_PER_FS:-'0'} 60 export PERF_SYNC_TYPES=${PERF_SYNC_TYPES:-'0 1'} 61 export PERF_IOSIZES='' # bssplit used instead 62elif [[ -n $PERF_REGRESSION_NIGHTLY ]]; then 63 export PERF_RUNTIME=${PERF_RUNTIME:-$PERF_RUNTIME_NIGHTLY} 64 export PERF_RUNTYPE=${PERF_RUNTYPE:-'nightly'} 65 export PERF_NTHREADS=${PERF_NTHREADS:-'32 64'} 66 export PERF_NTHREADS_PER_FS=${PERF_NTHREADS_PER_FS:-'0'} 67 export PERF_SYNC_TYPES=${PERF_SYNC_TYPES:-'1'} 68 export PERF_IOSIZES='' # bssplit used instead 69fi 70 71# Layout the files to be used by the readwrite tests.
