This code is for benchmarking the performance impacts of using different types of ID for the primary key in a database, but can be easily modified to benchmark other aspects.

Steps

• Run composer install to install the necessary packages.
• Set up a MySQL database somewhere and make it remotely accessible.
• Fill in the connection details for that database in the settings.php.tmpl file
• Rename the settings.php.tmpl file to settings.php
• Execute the main.php script.
• Look in the results folder for the time the queries took and how long each test took to run. If the test took a long time to run, but the queries were fast, this tells you that the generation of the UUID was what made it slow.
