Apache & PHP system resource usage | mpm_prefork + mod_php vs. mpm_event + php-fpm
As descriped previously there are several different ways to serve dynamic requests via Apache. Today we will compare performance thanks to vegeta, a http load testing tool and library written in Go. To compare performance test duration has been fixed at 30 seconds and rate of requests increases from 10 to 50 requests per second. This suite of tests is running against WordPress 4.8.1 with PHP 7.1.7 [opcache and xdebug enabled] and Apache 2.4.27 [mpm_prefork + mod_php vs. mpm_event + php-fpm].
echo "GET https://example.com/wordpress/" | ./vegeta attack -insecure -duration=30s -rate=10 -keepalive=false | tee results.bin | ./vegeta report

As the PHP Community decided to publish another PHP release candidate people are getting more and more excited about the official release of PHP7. The release first was scheduled for 12th November but has been shifted to 26th November if no new critical Bugs are found in the newly released RC7.
