Speedora Total Website Speed Optimization vs Varnish/Nginx Proxy Caching

Speedora is a free, all-in-one speed plugin. It caches pages, minifies HTML/CSS/JS, lazy-loads media, converts images to WebP, and removes unused WordPress baggage. Settings are grouped by feature, and child options stay locked until their parent is enabled. Do not run Speedora page cache together with another page-cache plugin (WP Super Cache, W3 Total Cache, LiteSpeed Cache, and similar). Use one page cache at a time.

Varnish Caching sends a PURGE request to Varnish Cache / Nginx Proxy Cache when a page or post is modified. This occurs when editing, publishing, commenting or deleting an item, and when changing themes. Not all pages are purged every time, depending on your Varnish / Nginx Proxy Cache configuration. When a post, page, or custom post type is edited, or a new comment is added, only the following pages will purge: The front page The post/page edited Any categories or tags associated with the page Varnish Cache / Nginx Proxy Cache is a web application accelerator also known as a caching HTTP reverse proxy. You install it in front of any server that speaks HTTP and configure it to cache the contents. This plugin does not install Varnish/Nginx for you, nor does it configure Varnish/Nginx for WordPress. It’s expected you already did that on your own using the provided config files.
