This guide explains how to increase the max_children value on Serveur Cloud to increase the number of simultaneous PHP processes that can be used by your site. This will be very useful for resolving infinite page loading issues on your site.

Preamble

• By default, the limit for max_children is set to 20 for all hosting.
  • Although it is possible to increase this value from the Infomaniak Manager, the limit for max_children is automatically adjusted based on the configuration of your Cloud Server.
  • To increase this limit on shared hosting, migrate to Cloud Server.
• To understand how to calculate the max_children needed as accurately as possible, refer to this article on the subject.

Increase the max_children value

Prerequisites

• Ensure that you have the necessary resources on the Cloud Server.
• Ensure that all resources of the Cloud Server are not used; if it turns out that they are fully used, increasing the value of max_children will have no effect (Modify the resources of the Cloud Server).
• Monitor your server's resource usage, if your server's resources are maxed out, it will be necessary to check the optimization of your processes and site before considering increasing the max_children value.
• Check the PHP error reports from the /ik-logs folder (master process php logs - file name: php-fpm.log) to verify if the "max_children" limit has been exceeded... example of error: [05-Jul-2024 09:08:58] WARNING: [pool www.infomaniak.ch] server reached max_children setting (20), consider raising it
