Jun 3, 2019 · Memory management in a modern operating system is very complex. Instead of trying to work out how much RAM each process needs individually, I suggest either using cgroups to limit the total amount of RAM all php-fpm processes together can consume, or at least using cgroups to track their total usage and adjust their number based on that.

Aug 12, 2022 · Depending on your specific app, a single page request may require a PHP-FPM worker with roughly 80MB minimum RAM alone.

When the website is under load, each PHP5-FPM process has very high CPU usage but I have yet to see a process go over 1% RAM usage. Everywhere that I look (eg here and here ) only talks about increases of pm.max_children being limited by RAM, and doesn't mention CPU usage.

Mar 28, 2023 · My Memory and swap memory is being used mostly by php-fpm which results in slow response from server. below is the output of top command. Kindly suggest. Also my php-fpm conf file settings are as follows: pm = ondemand pm.max_children = 250 pm.process_idle_timeout = 3600s; pm.max_requests = 500
