PHP 7 instant speed boost
It took me a while to notice the arrival of PHP 7, i don't recall ever seeing PHP 6 on offer in cPanel?
Just a heads up to anyone reading this that doesn't concern themselves with things like which version of PHP to use, if you select #7, you should notice a big difference.
It wont make images load faster, nor server anything faster besides PHP. Html websites wont benefit obviously, but WordPress or any other PHP framework should render PHP pages much quicker.
Keep in mind that once you have switched it over in cPanel, you ought to make sure your site is working! But if everything is up to date and best practices were followed, then it'll be swoit!
