This script tests the disk performance using fio tool

Define test parameters

blocksize='4k' iodepth='32' size='1G' runtime='30s' filename='/tmp/testfile'

Define test functions

function run_test() { local testname=$1 local cmd="fio --name=$testname --ioengine=libaio --bs=$blocksize --iodepth=$iodepth --size=$size --runtime=$runtime --filename=$filename --time_based --output-format=json" local result=$(eval $cmd) echo $result }

function print_test_results() { local result=$1 local bw=$(echo $result | jq '.jobs[0].write.bw') local iops=$(echo $result | jq '.jobs[0].write.iops') echo 'Write bandwidth: $bw' echo 'Write IOPS: $iops' }

Run tests

echo 'Running tests...' echo '' echo 'Sequential write test' result=$(run_test 'sequential-write') print_test_results $result echo '' echo 'Random write test' result=$(run_test 'random-write') print_test_results $result

Clean up

rm -f $filename

echo 'Tests finished!'
