Since the new version of PHP i.e. PHP 7 is due to be released in November 2015. PHP is the programming language that Moodle is written in and is known as the server side scripting language.
Catalyst NZ the Moodle Partner from New Zealand have shared their tests of Moodle with PHP 7. The main improvement of using Moodle with PHP 7 is the Speed which may result in more requests your web hosting infrastructure can handle in a given time period.
The only difference between tests runs was the version of PHP which shows a performance increase for PHP7. PHP7 completed the 10,000 requests 12% faster than PHP5.6. With 95% of requests taking 16% less time to complete with PHP7.
