This document summarizes performance testing done on a Magento 2 store using different PHP versions and configurations. It tested Magento 2 performance using PHP 5.6 alone and with Varnish, PHP 7 alone and with Varnish, and compared PHP 5.6 to PHP 7. The tests measured transaction rate, number of transactions and response time. The results showed that using PHP 7 alone or with Varnish provided a higher transaction rate and lower response times compared to PHP 5.6. Caching pages with Varnish also improved performance for both PHP 5.6 and 7 by increasing transaction rates and reducing response times.
