On the Symfony Finland site they've post together a post sharing some benchmark results of Symfony on PHP 7.0 versus 7.1, the most recent major release of the PHP language with some improvements of its own.
PHP 7.1 was launched on December 1st 2016. This was the first minor release after the release of 7.0 a year ago. PHP 7.0 was a revolutionary product, especially when it comes to memory usage and performance. PHP 7.1 is a more modest upgrade that brings new features and improved performance. But how much has performance improved from a year back?
The benchmarking uses the eZ Platform demo running a full CMS similar to the previous benchmarking done in 2015. The checks were run using:
- a "clean" environment (no caching, PHP-FPM just restarted and no APC cache)
- standard requests running in development mode
- more requests but this time in production mode
The post shares the results with a few graphs showing them in terms of response time for both sequential and concurrent page requests.
