Magento How to config PageSpeed with Magento?

Centmin Mod is provide as is, so short of scripted related bugs or issues, any further optimisation to the web stack components - nginx, php-fpm, mariadb mysql, csf firewall etc or web app specific configurations are left to the Centmin Mod user to deal with. So I do not provide any free support for such.

However, Centmin Mod users are free to help each other out and ask questions or give answers on this community forum. My hopes are that this community forum evolves so that more veteran long time Centmin Mod users help new Centmin Mod users out

So best way to do it is enable ngx_pagespeed and trial and error testing using ngx_pagespeed troubelshooting steps below.

You'd have to troubleshoot and tweak it yourself following these guides and info outlined below

• This thread is an example of such tweaking for Xenforo Nginx PageSpeed - This forum's pagespeed.conf

FYI, I've never used Magento either
