Update 12.10.2015: PHP 7 with OpCache is now available at 1&1. Your Managed WordPress websites are updated automatically.
With PHP 7 + OpCache, WordPress websites run more than twice as fast as with PHP 5.6. PHP 7 impressed us in numerous tests, which is why we have been using a release candidate of PHP 7 with OpCache active that we tested for all Managed WordPress packages from day one.
With the release of the final version of PHP 7, we will automatically switch your websites to this version in the coming days. This update will improve their speed even more.
How OpCache works
Usually, PHP scripts are always compiled at runtime. In this process, part of the computing time is needed to convert the code. With OpCache, this calculation is only performed once, and the pre-compiled, machine-readable (calculated) script is saved in a cache. The script can be loaded from this cache at lightning speed as needed. In most cases, this significantly improves the speed.
Large websites in particular can handle a considerably larger number of requests at the same time when OpCache is enabled – this is especially important for company websites and e-commerce.
PHP 7 with OpCache rounds out our hardware that is fine-tuned for Managed WordPress and uses full SSD and DDoS protection to speed up your page and protect it from attacks.
Enable PHP 7 for other packages
We will offer PHP 7 for other packages. At the moment, we offer you the option of using the PHP settings in the 1&1 Control Panel to enable and test PHP 7 release candidates in advance.
