WordPress stack

See stickied post  is a good place to start.

We all have our preferred tools that work best for us (my agency's stack is listed here ), but you must find out which tools work the best for you. Don't listen blindly to others; test tools and see what you prefer the most.

See my pagespeed optimization guide here for a performance optimized Wordpress stack:

The document outline icon on the top left (Desktop) opens the table of contents.

There's an extensive amount of optimization information and resources for server stack configuration for NGINX, Apache, OpenLiteSpeed, Varnish, Object Caching, PHP, HAProxy, MySQL, SSL, Gzip/Brotli, HTTP/2 and HTTP/3, the Google Pagespeed module, Security considerations effects on performance and Linux optimizations. There are also a bunch of resources on database optimization.

Wordpress specific optimizations: Sections on Ads, Forms, Woocommerce, Analytics, Google Maps, Fonts, Custom Fields, Galleries, Video Players, Sliders, Filters, Recipes, Charts, Tables, Animations, SEO plugins, Anti-Spam, Cookie Notices, Backup plugins; in addition to one size fits all optimizations(Images, Videos, CDN, SSL, CSS, JS, Resource Hints, Caching etc), and a bunch more.

I'm trying to holistically cover every aspect from top to bottom, so if there are any gaps you would like me to fill, let me know.
