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. $STF_SUITE/tests/perf/perf.shlib 39 40function cleanup 41{ 42 # kill fio and iostat 43 pkill fio 44 pkill iostat 45 recreate_perf_pool 46} 47 48trap "log_fail \"Measure IO stats during random read load\"" SIGTERM 49log_onexit cleanup 50 51recreate_perf_pool 52populate_perf_filesystems 53 54# Aim to fill the pool to 50% capacity while accounting for a 3x compressratio. 55export TOTAL_SIZE=$(($(get_prop avail $PERFPOOL) * 3 / 2)) 56 57# Variables for use by fio. 58if [[ -n $PERF_REGRESSION_WEEKLY ]]; then 59 export PERF_RUNTIME=${PERF_RUNTIME:-$PERF_RUNTIME_WEEKLY} 60 export PERF_RANDSEED=${PERF_RANDSEED:-'1234'} 61 export PERF_COMPPERCENT=${PERF_COMPPERCENT:-'66'} 62 export PERF_COMPCHUNK=${PERF_COMPCHUNK:-'4096'} 63 export PERF_RUNTYPE=${PERF_RUNTYPE:-'weekly'} 64 export PERF_NTHREADS=${PERF_NTHREADS:-'1 4 8 16 32 64 128'} 65 export PERF_NTHREADS_PER_FS=${PERF_NTHREADS_PER_FS:-'0'} 66 export PERF_SYNC_TYPES=${PERF_SYNC_TYPES:-'0 1'} 67 export PERF_IOSIZES=${PERF_IOSIZES:-'8k 64k 256k'} 68elif [[ -n $PERF_REGRESSION_NIGHTLY ]]; then 69 export PERF_RUNTIME=${PERF_RUNTIME:-$PERF_RUNTIME_NIGHTLY} 70 export PERF_RANDSEED=${PERF_RANDSEED:-'1234'} 71 export PERF_COMPPERCENT=${PERF_COMPPERCENT:-'66'} 72 export PERF_COMPCHUNK=${PERF_COMPCHUNK:-'4096'} 73 export PERF_RUNTYPE=${PERF_RUNTYPE:-'nightly'} 74 export PERF_NTHREADS=${PERF_NTHREADS:-'16 32'} 75 export PERF_NTHREADS_PER_FS=${PERF_NTHREADS_PER_FS:-'0'} 76 export PERF_SYNC_TYPES=${PERF_SYNC_TYPES:-'1'} 77 export PERF_IOSIZES=${PERF_IOSIZES:-'8k 128k 1m'} 78fi 79 80# Set up the scripts and output files that will log performance data. 81lun_list=$(pool_to_lun_list $PERFPOOL) 82log_note "Collecting backend IO stats with lun list $lun_list" 83if is_linux; then 84 typeset perf_record_cmd="perf record -F 99 -a -g -q \ 85 -o /dev/stdout -- sleep ${PERF_RUNTIME}" 86 87 export collect_scripts=( 88 "zpool iostat -lpvyL $PERFPOOL 1" "zpool.iostat" 89 "vmstat -t 1" "vmstat" 90 "mpstat -P ALL 1" "mpstat" 91 "iostat -tdxyz 1" "iostat" 92 "$perf_record_cmd" "perf" 93 ) 94else 95 export collect_scripts=( 96 "$PERF_SCRIPTS/io.d $PERFPOOL $lun_list 1" "io" 97 "vmstat -T d 1" "vmstat" 98 "mpstat -T d 1" "mpstat" 99 "iostat -T d -xcnz 1" "iostat" 100 ) 101fi 102 103log_note "Sequential writes with $PERF_RUNTYPE settings" 104do_fio_run sequential_writes.fio true false 105log_pass "Measure IO stats during sequential write load" 106
