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. # . $STF_SUITE/include/libtest.shlib . $STF_SUITE/tests/perf/perf.shlib function cleanup { # kill fio and iostat pkill fio pkill iostat recreate_perf_pool } trap "log_fail \"Measure IO stats during random read load\"" SIGTERM log_onexit cleanup recreate_perf_pool populate_perf_filesystems # Aim to fill the pool to 50% capacity while accounting for a 3x compressratio. export TOTAL_SIZE=$(($(get_prop avail $PERFPOOL) * 3 / 2)) # Variables for use by fio. if [[ -n $PERF_REGRESSION_WEEKLY ]]; then export PERF_RUNTIME=${PERF_RUNTIME:-$PERF_RUNTIME_WEEKLY} export PERF_RANDSEED=${PERF_RANDSEED:-'1234'} export PERF_COMPPERCENT=${PERF_COMPPERCENT:-'66'} export PERF_COMPCHUNK=${PERF_COMPCHUNK:-'4096'} export PERF_RUNTYPE=${PERF_RUNTYPE:-'weekly'} export PERF_NTHREADS=${PERF_NTHREADS:-'1 4 8 16 32 64 128'} export PERF_NTHREADS_PER_FS=${PERF_NTHREADS_PER_FS:-'0'} export PERF_SYNC_TYPES=${PERF_SYNC_TYPES:-'0 1'} export PERF_IOSIZES=${PERF_IOSIZES:-'8k 64k 256k'} elif [[ -n $PERF_REGRESSION_NIGHTLY ]]; then export PERF_RUNTIME=${PERF_RUNTIME:-$PERF_RUNTIME_NIGHTLY} export PERF_RANDSEED=${PERF_RANDSEED:-'1234'} export PERF_COMPPERCENT=${PERF_COMPPERCENT:-'66'} export PERF_COMPCHUNK=${PERF_COMPCHUNK:-'4096'} export PERF_RUNTYPE=${PERF_RUNTYPE:-'nightly'} export PERF_NTHREADS=${PERF_NTHREADS:-'16 32'} export PERF_NTHREADS_PER_FS=${PERF_NTHREADS_PER_FS:-'0'} export PERF_SYNC_TYPES=${PERF_SYNC_TYPES:-'1'} export PERF_IOSIZES=${PERF_IOSIZES:-'8k 128k 1m'} fi # Set up the scripts and output files that will log performance data. lun_list=$(pool_to_lun_list $PERFPOOL) log_note "Collecting backend IO stats with lun list $lun_list" if is_linux; then typeset perf_record_cmd="perf record -F 99 -a -g -q \ -o /dev/stdout -- sleep ${PERF_RUNTIME}" export collect_scripts=( "zpool iostat -lpvyL $PERFPOOL 1" "zpool.iostat" "vmstat -t 1" "vmstat" "mpstat -P ALL 1" "mpstat" "iostat -tdxyz 1" "iostat" "$perf_record_cmd" "perf" ) else export collect_scripts=( "$PERF_SCRIPTS/io.d $PERFPOOL $lun_list 1" "io" "vmstat -T d 1" "vmstat" "mpstat -T d 1" "mpstat" "iostat -T d -xcnz 1" "iostat" ) fi log_note "Sequential writes with $PERF_RUNTYPE settings" do_fio_run sequential_writes.fio true false log_pass "Measure IO stats during sequential write load"
