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. 35# 36 37. $STF_SUITE/include/libtest.shlib 38. $STF_SUITE/tests/perf/perf.shlib 39 40log_assert "Measure IO stats during sequential write load" 41log_onexit cleanup 42 43function cleanup 44{ 45 log_must zfs destroy $TESTFS 46} 47 48export TESTFS=$PERFPOOL/testfs 49recreate_perfpool 50log_must zfs create $PERF_FS_OPTS $TESTFS 51 52# Aim to fill the pool to 50% capacity while accounting for a 3x compressratio. 53export TOTAL_SIZE=$(($(get_prop avail $TESTFS) * 3 / 2)) 54 55# Variables for use by fio. 56if [[ -n $PERF_REGRESSION_WEEKLY ]]; then 57 export PERF_RUNTIME=${PERF_RUNTIME:-$PERF_RUNTIME_WEEKLY} 58 export PERF_RUNTYPE=${PERF_RUNTYPE:-'weekly'} 59 export PERF_NTHREADS=${PERF_NTHREADS:-'1 4 8 16 32 64 128'} 60 export PERF_SYNC_TYPES=${PERF_SYNC_TYPES:-'0 1'} 61 export PERF_IOSIZES=${PERF_IOSIZES:-'8k 128k 1m'} 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=${PERF_NTHREADS:-'16 32'} 66 export PERF_SYNC_TYPES=${PERF_SYNC_TYPES:-'1'} 67 export PERF_IOSIZES=${PERF_IOSIZES:-'8k 128k 1m'} 68fi 69 70# Set up the scripts and output files that will log performance data. 71lun_list=$(pool_to_lun_list $PERFPOOL) 72log_note "Collecting backend IO stats with lun list $lun_list" 73export collect_scripts=("dtrace -s $PERF_SCRIPTS/io.d $PERFPOOL $lun_list 1" 74 "io" "vmstat 1" "vmstat" "mpstat 1" "mpstat" "iostat -xcnz 1" "iostat" 75 "dtrace -s $PERF_SCRIPTS/profile.d" "profile" "kstat zfs:0 1" "kstat") 76 77log_note "Sequential writes with $PERF_RUNTYPE settings" 78do_fio_run sequential_writes.fio true false 79log_pass "Measure IO stats during sequential write load" 80
