Did you know that the latest PHP family 7 is twice as fast as the default 5.6 that around 50% of websites still use today? Here you can see a detailed benchmark made by Zend where we can see the comparison using the most popular CMS like WordPress.
We highly recommend all our clients to upgrade as soon as possible to the latest PHP7.2 that is already installed in all servers. However, make sure to always download a backup before and make a PHP Version Compatibility Assessment.
