1. Install Composer - Dependency Manager for PHP

https://getcomposer.org/

Windows

Download and run Composer-Setup.exe https://getcomposer.org/Composer-Setup.exe

UNIX

php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
php -r "if (hash_file('SHA384', 'composer-setup.php') === '669656bab3166a7aff8a7506b8cb2d1c292f042046c5a994c43155c0be6190fa0355160742ab2e1c88d40d5be660b410') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
php composer-setup.php
php -r "unlink('composer-setup.php');"
mv composer.phar /usr/local/bin/composer

2. Install PHPBench - A Benchmark Runner for PHP

http://phpbench.readthedocs.io/en/latest/

Make sure git is installed and in your PATH env. Navigate into Performance folder and run:

composer install

3. Run benchmarks

PHPBench will use the default PHP in PATH env. To specify a different PHP binary, use --php-binary path_to_php. Make sure sqlsrv and pdo_sqlsrv are loaded. Edit lib/connect.php with connection credentials. Run benchmarks.

Run sqlsrv benchmarks:

./vendor/bin/phpbench run benchmark/sqlsrv/regular --time-unit="milliseconds" --iterations [num_of_iterations] --report=aggregate

Run pdo_sqlsrv benchmarks:

./vendor/bin/phpbench run benchmark/pdo_sqlsrv/regular --time-unit="milliseconds" --iterations [num_of_iterations] --report=aggregate

Run benchmarks that fetch large dataset. These benchmarks assume the database is already populated with data.

./vendor/bin/phpbench run benchmark/sqlsrv/large --time-unit="milliseconds" --report=aggregate
./vendor/bin/phpbench run benchmark/pdo_sqlsrv/large --time-unit="milliseconds" --report=aggregate
