This document summarizes the results of performance tests conducted on a Magento 2 store using different PHP versions and configurations. The tests measured the transaction rate, number of transactions, and response time of Magento 2 using PHP 5.6 alone, PHP 5.6 with Varnish, PHP 7 alone, and PHP 7 with Varnish. The main findings were that PHP 7 significantly outperformed PHP 5.6, and that adding Varnish provided major improvements when combined with both PHP 5.6 and PHP 7, especially in terms reducing response times.
