PHP-FPM Optimization Request

[Douglas Taylor]

I have a 4-core( Intel Xeon 3.1 ghz) processer with 16 GB RAM, dedicated server, primarily one domain.

Anyone have any suggestions for optimizing php-fpm in terms of “Max Requests”, “Max-Children” and “Process Idle Timeout” and ”Max Servers”?

Thanks in advance!

Here is a start point to read about this.

Determining the correct number of child processes for PHP-FPM on NGinx

If you are using a NGinx webserver with PHP-FPM most likely you will have to adjust the "out of the box" settings of php-fpm. If your php-fpm.log file…

My own config for every server

pm = dynamic
pm.max_children = cpu x 4
pm.start_servers = cpu x 2
pm.min_spare_servers = # of cpu
pm.max_spare_servers = cpu x 3
pm.max_requests = 5000

hi
cpu means the number of cores or thread?

Total CPU threads if you're on a dedicated server; total CPU cores if you're on a VPS.

Let's take a very quick look at how best to set up PHP-FPM for high throughput, low latency, and more stable CPU and memory use. By default, most setups
