Custom system benchmark script for Centmin Mod LEMP web stack users.

Development is ongoing so please test only on test servers and not production live servers.

Current Test Suite

• disk dd, ioping, fio
• ping, mtr
• memory bandwidth testing tmpfs ramdisk with disk dd and ioping
• single threaded wget bandwidth benchmarks
• parallel multi threaded axel bandwidth benchmarks [Centmin Mod stack only]
• OpenSSL system benchmark
• test system entropy_avail (entropy pool availability - closer to 4096 bits = better randomness and SSL related performance vs closer to 0 kernel block at generating random data = poorer SSL performance) mentioned
• rngtest suite - check the randomness of data (currently disabled by default / not yet developed)
• Nginx static OpenSSL benchmarks [Centmin Mod stack only]
• mysqlslap http://dev.mysql.com/doc/refman/5.6/en/mysqlslap.html
• PHP (php-fpm) Zend/bench.php & Zend/micro_bench.php [Centmin Mod stack only]
• UnixBench 5.1.3 (currently disabled by default)
• ServerBear.com tests (currently disabled by default / not yet developed)
• compression/decompression tests (not yet developed)

To run type in SSH window as root user:

curl -sL https://github.com/centminmod/centminmodbench/raw/master/centminmodbench.sh | bash

If you want to download to server and run in SSH window as root user:

mkdir -p /root/tools
cd /root/tools
yum -y install wget
wget -O centminmodbench.sh https://github.com/centminmod/centminmodbench/raw/master/centminmodbench.sh
chmod +x centminmodbench.sh

If you want to enable UnixBench

sed -i "s|RUN_UNIXBENCH=.*|RUN_UNIXBENCH='y'|" /root/tools/centminmodbench.sh

To run script locally in SSH window as root user type:

/root/tools/centminmodbench.sh

If you don't want SSH session's connection drop out to abort your benchmark run you can run the script via screen window by installing screen via YUM and then launch centminmodbench.sh via screen

yum -y install screen
screen -dmS bench 
screen -r bench
/root/tools/centminmodbench.sh

If your SSH session drops out, the script is still running via the screen session called bench. You can use this command to view available sessions:

 screen -ls

Sample output

There is a screen on:
        2136.bench      (Detached)
1 Socket in /var/run/screen/S-root.

To reattach the session named bench to continue with the benchmark or find the completed benchmark output, type:

screen -r bench

To update script

wget -O /root/tools/centminmodbench.sh https://github.com/centminmod/centminmodbench/raw/master/centminmodbench.sh

To remove centminmodbench.sh and log files

/root/tools/centminmodbench.sh cleanup

Or manually remove the following directories and file

/home/centminmodbench
/home/centminmodbench_logs
/home/mysqlslap
/home/phpbench_logs
/root/tools/centminmodbench.sh

Default log directories include:

• BENCHDIR='/home/centminmodbench' (source downloads location)
• LOGDIR='/home/centminmodbench_logs' (benchmark results logs)
• MYSQLSLAP_DIR='/home/mysqlslap' (mysqlslap results logs)
• PHPBENCHLOGDIR='/home/phpbench_logs' (PHP-FPM benchmark logs)

Variables you can alter within centminmodbench.sh. Note the bandwidth tests can be set regionally as well, so if you have no need for Asia tests, you can turn the Asian specific bandwidth tests off etc. UnixBench is turned off by default during testing of this script as it adds up to 30-60 minutes to test runs as seen at https://community.centminmod.com/threads/centminmodbench-sh-benchmark-script-for-centmin-mod-lemp-servers.1298/#post-5880.

Centmin Mod Install + Benchmark Extended

If you want to automate both Centmin Mod installation + centminmodbench.sh run + extended Nginx HTTP/2 HTTPS RSA 2048 bit + ECDSA 256bit SSL certificated based h2load tests, zcat/pzcat log processing tests and redis benchmark tests, you can use the below commands. The Nginx HTTP/2 HTTPS h2load tests will test 4 sets of SSL Ciphers for ECDHE-RSA-AES128-GCM-SHA256, ECDHE-RSA-AES256-GCM-SHA384, ECDHE-ECDSA-AES128-GCM-SHA256 and ECDHE-ECDSA-AES256-GCM-SHA384. This test may take over 60-120 minutes to complete depending on your server hardware specs i.e. number of cpu cores, cpu clock speed, memory bandwidth speed, disk I/O performance and network connectivity speed etc. As such test should be run in screen session so it survives SSH session disconnection. All of the scripts output and benchmark results will be logged into a file at /root/centminlogs/centminmod-benchmark-all-${DT}.log where ${DT} is date timestamp.

mkdir -p /root/tools
cd /root/tools
yum -y install wget
wget -O installnbench2.sh https://github.com/centminmod/centminmodbench/raw/master/installnbench2.sh
chmod +x installnbench2.sh
yum -y install screen
screen -dmS installnbench
screen -r installnbench
time /root/tools/installnbench2.sh

If your SSH session drops out, the script is still running via the screen session called bench. You can use this command to view available sessions:

 screen -ls

Sample output

There is a screen on:
        2136.installnbench      (Detached)
1 Socket in /var/run/screen/S-root.

To reattach the session named bench to continue with the benchmark or find the completed benchmark output, type:

screen -r installnbench

To update script

wget -O /root/tools/installnbench2.sh https://github.com/centminmod/centminmodbench/raw/master/installnbench2.sh

Benchmark Extended Only

If you want to automate on existing Centmin Mod installs both centminmodbench.sh run + extended Nginx HTTP/2 HTTPS RSA 2048 bit + ECDSA 256bit SSL certificated based h2load tests, zcat/pzcat log processing tests and redis benchmark tests, you can use the below commands. The Nginx HTTP/2 HTTPS h2load tests will test 4 sets of SSL Ciphers for ECDHE-RSA-AES128-GCM-SHA256, ECDHE-RSA-AES256-GCM-SHA384, ECDHE-ECDSA-AES128-GCM-SHA256 and ECDHE-ECDSA-AES256-GCM-SHA384. This test may take over 60-120 minutes to complete depending on your server hardware specs i.e. number of cpu cores, cpu clock speed, memory bandwidth speed, disk I/O performance and network connectivity speed etc. As such test should be run in screen session so it survives SSH session disconnection. All of the scripts output and benchmark results will be logged into a file at /root/centminlogs/centminmod-fullbench-all-${DT}.log where ${DT} is date timestamp.

mkdir -p /root/tools
yum -y install wget
cd /root/tools
wget -O fullbench.sh https://github.com/centminmod/centminmodbench/raw/master/fullbench.sh
chmod +x fullbench.sh
yum -y install screen
screen -dmS fullbench
screen -r fullbench
time /root/tools/fullbench.sh

If your SSH session drops out, the script is still running via the screen session called bench. You can use this command to view available sessions:

 screen -ls

Sample output

There is a screen on:
        2136.fullbench      (Detached)
1 Socket in /var/run/screen/S-root.

To reattach the session named bench to continue with the benchmark or find the completed benchmark output, type:

Nginx HTTP/2 HTTPS h2load Benchmarks

• If you want to run on existing Centmin Mod Nginx installs an extended Nginx HTTP/2 HTTPS RSA 2048 bit + ECDSA 256bit SSL certificated based h2load tests, you can use the below commands.
• h2load HTTP/2 HTTPS load test tool will be run single threaded so tests only 1 cpu core of the system.
• https_bench.sh will create a dummy Nginx HTTP/2 HTTPS vhost called http2.domain.com and setup both self-signed RSA 2048bit and ECDSA 256bit SSL certificates on the dummy Nginx vhost to run h2load HTTP/2 HTTPS load tests against. After https_bench.sh completes, it will automatically remove the http2.domain.com dummy Nginx vhost site and all SSL certificates.
• The Nginx HTTP/2 HTTPS h2load tests will test 4 sets of SSL Ciphers for ECDHE-RSA-AES128-GCM-SHA256, ECDHE-RSA-AES256-GCM-SHA384, ECDHE-ECDSA-AES128-GCM-SHA256 and ECDHE-ECDSA-AES256-GCM-SHA384.
• This test will test gzip (and brotli if Nginx support is detected) HTTP compression load tests using h2load HTTP/2 HTTPS tester tool.
• These test should be run in screen session so it survives SSH session disconnection.
• All of the scripts output and benchmark results will be logged into a file at /root/centminlogs/h2load-nginx-https-${DT}.log where ${DT} is date timestamp.

h2load HTTP/2 HTTPS load test configurations

There's 8x h2load test configurations in total:
