The ARC is cleared with `zinject -a` prior to 26# each run so reads will go to disk. 27# 28 29. $STF_SUITE/include/libtest.shlib 30. $STF_SUITE/tests/perf/perf.shlib 31 32function cleanup 33{ 34 log_must zfs destroy $TESTFS 35} 36 37log_assert "Measure IO stats during random read-write load" 38log_onexit cleanup 39 40export TESTFS=$PERFPOOL/testfs 41recreate_perfpool 42log_must zfs create $PERF_FS_OPTS $TESTFS 43 44# Aim to fill the pool to 50% capacity while accounting for a 3x compressratio. 45export TOTAL_SIZE=$(($(get_prop avail $TESTFS) * 3 / 2)) 46 47# Variables for use by fio. 48if [[ -n $PERF_REGRESSION_WEEKLY ]]; then 49 export PERF_RUNTIME=${PERF_RUNTIME:-$PERF_RUNTIME_WEEKLY} 50 export PERF_RUNTYPE=${PERF_RUNTYPE:-'weekly'} 51 export PERF_NTHREADS=${PERF_NTHREADS:-'8 16 64'} 52 export PERF_SYNC_TYPES=${PERF_SYNC_TYPES:-'0 1'} 53 export PERF_IOSIZES='' # bssplit used instead 54elif [[ -n $PERF_REGRESSION_NIGHTLY ]]; then 55 export PERF_RUNTIME=${PERF_RUNTIME:-$PERF_RUNTIME_NIGHTLY} 56 export PERF_RUNTYPE=${PERF_RUNTYPE:-'nightly'} 57 export PERF_NTHREADS=${PERF_NTHREADS:-'64 128'} 58 export PERF_SYNC_TYPES=${PERF_SYNC_TYPES:-'1'} 59 export PERF_IOSIZES='' # bssplit used instead 60fi 61 62# Layout the files to be used by the readwrite tests.
