Enable PHP 7 and measure performance
Enable PHP 7 with the web server.
[root@ip ~]# systemctl enable php-fpm [root@ip ~]# systemctl restart php-fpm
Load the front page in your browser. After a few refreshes the page load time will increase. In my environment, my page load time was 18ms. This is about the limit that can be measured with the browser.
Perform a benchmark test with ab. In order to prevent inconsistencies, change the requests from 100 to 300 and concurrent requests from 10 to 30.
[root@ip ~]# ab -n 300 -c 30 http://ec2-xxx.xxx.compute.amazonaws.com/
In my environment, requests per second was 148.08. Just by changing to PHP 7, our performance increased two-fold over PHP 5.6. And we now have 12.5x the speed of the default environment.
|Tuning contents||Page load time||Requests per second|
|MariaDB settings||64ms (275%)||31.82|
|Translation accelerator (cache)||53ms (332%)||39.29|
|Translation accelerator (disabled)||36ms (488%)||56.78|
|Tuned settings||34ms (517%)||58.47|
|event MPM+php-fpm||33ms (537%)||60.79|
|AWS users||31ms (567%)||71.76|
|PHP 5.6+OPCache+APCu||32ms (550%)||61.84 (550.2%)|
|PHP 7+OPCache+APCu||18ms (977.7%)||148.08 (1250.6%)|
Next time, we will install the PHP-compatible execution environment HHVM (HipHop Virtual Machine) developed by Facebook, and achieve 16.9x more performance than the default environment.
