Hello Guys, I am setting up a new commercial project which is expected to serve, hopefully, 100,000 visitors per day. As you know, Apache2 mpm_prefork is very slow. So, I plan to switch to Apache v2.4 mpm_event OR Nginx 1.10. I follow this procedure: Turn off mpm_prefork and php7.0 apache2 modules; Turn on apache2 php7.0-fpm.conf; Turn on mpm_event apache2 module and then restart apache2. Yes, Apache2 starts and runs. Now, my question is: Is the above procedure all I need to ensure that mpm_event runs stably? Will php7.0 work well yet with Apache2 server after php7.0 module has been unloaded? Will some of those php 7.0 extensions stop working? Is my mpm_event setup as fast as a Nginx server setup? My system is ISPConfig 3.1.11, Ubuntu 16.04.4 amd64, Apache v2.4.18, php 7.0.30. Hope to hear your valuable opinions as soon as possible.
