Most of you might know by now that we made PHP 7 as the default PHP version on all the new servers. We made this decision based on the benchmarks that showed that PHP 7 performs way better than applications and websites running on PHP 5.6.
We recently ran tests on Symfony 3 on following configuration.
Server: 8GB DigitalOcean
No caching libraries
Test Duration: 5 min
No of Users: 250
Case 1: PHP 5.6, DigitalOcean 8GB
Case 2: PHP 7, DigitalOcean 8GB
