Linux Server Benchmarking Scripts
Quickly Benchmark CPU & HDD

Linux Benchmark Shell Scripts
Current tests include CPU & HDD from sysbench
(will auto install on Debian/Ubuntu flavors.)
Goal: To avoid remembering arguments for performance utilities. Written in bash.
Step 1: SETUP BENCHMARK:
# Create folder for results & scriptsexport BENCH_DIR=$HOME/benchmarksmkdir -p $BENCH_DIR/results
Step 2: CREATE SHORTCUT SCRIPT: $HOME/benchmarks/bench-library.sh
#!/bin/bashset -e
# Install some depsif [ "$(which sysbench)" == "" -o "$(which inxi)" == "" -o "$(which tcpdump)" == "" ]; then sudo apt-get update && apt-get install -y sysbench inxi htop iotop tcpdump hddtempfi# Variablesexport DATE_TAG=`date +%F` #YYYY-MM-DDexport CPU_CORES="$([ -e /proc/cpuinfo ] && grep -sc ^processor /proc/cpuinfo || sysctl -n hw.ncpu)"export BENCH_DIR=$HOME/benchmarks/
mkdir -p $BENCH_DIR
function benchCpu() { thread_limit=${1:$CPU_CORES} prime_limit=${2:-20000}
if [ $CPU_CORES -lt `expr 1 + $thread_limit` ]; then printf "\n\n${yellow}ALERT: Skipping tests limited by \"${thread_limit} thread test\"\n${cyan}Not enough CPU Cores ($CPU_CORES) ${reset}\n\n" else printf "\n\n${yellow}ALERT: Skipping tests limited by \"${thread_limit} thread test\"\n${reset}"
sudo sysbench --test=cpu \ --cpu-max-prime=${prime_limit} \ --num-threads=${CPU_CORES} \ run | tee -a $BENCH_DIR/results/cpu-test.log fi}
# benchSingleDisk seqrd 120G 8K 300function benchSingleDisk () { sudo sysbench --test=fileio --init-rng=on --file-test-mode=${1:-seqrd} --file-block-size=${3:-64K} \ --num-threads=${CPU_CORES} --max-time=${4:-180} --file-total-size=${2:-60G} \ --max-requests=0 run | tee -a $BENCH_DIR/results/sysbench-fileio.log}
# benchDisk - tests random read & write, and sequential r, and sequential write, before final cleanup.function benchDisk() { # Generates test files - up to 75% of your free space - in local dir, then runs the 3 tests (up to 20 minutes each) freeSpace=`df -k . | tail -1 | awk '{print $4}'` freeSpace="${freeSpace//G|T/}" testSize=$(awk "BEGIN {print ($freeSpace / 1024 / 1024) * 0.75; exit}") testSize=${testSize}G printf "####>>> \nWriting $testSize test data to ${PWD}...\n"
benchSingleDisk seqrd ${testSize} 8K 300 benchSingleDisk seqwr ${testSize} 8K 300 benchSingleDisk seqrw ${testSize} 8K 300 benchSingleDisk rndrd ${testSize} 8K 300 benchSingleDisk rndwr ${testSize} 8K 300 benchSingleDisk rndrw ${testSize} 8K 300

printf "\n\n####>>> \nCOMPLETED TESTS! Great Success!!! \n\n\n"}
Step 3: Set script permissions
chmod +x $BENCH_DIR/*.shsource $HOME/benchmarks/bench-library.sh
Step 4: CREATE BATCH RUNNER SCRIPT (OPTIONAL)
$HOME/benchmarks/run-bench.sh
#!/bin/bashset -e
source ./bench-library.sh
# Benchmark HDD Speed (in Current Directory)###########benchDisk
# Benchmark CPU - trying different thread counts (and work sizes)# It'll automatically skip test if we don't have enough cores (to have an impact)# NB: results comparable between different hardware - up to their same CPU CORE #.###########benchCpu 1benchCpu 4benchCpu 8 50000benchCpu 12 100000benchCpu 16 100000benchCpu 32 250000benchCpu 48 500000benchCpu 64 2000000
And now add execute permissions:
chmod +x $BENCH_DIR/*.sh
Usage
Make sure to source ~/benchmarks/bench-library.sh
, then run benchCpu
or benchDisk
.
