When tested Laravel 5.4 on [PHP 5 vs 7](https://www.cloudways.com/blog/laravel-5-benchmarks-php-5-6-and-7/) for performance benchmark, the latter was 50% faster than the previous version. With PHP 5.4, the response time was 553ms, whereas with PHP 7 it was 274ms. This is enough to prove that it is time to start upgrading to PHP 7 and make websites load faster.
