W3 Total Cache improves the user experience of your blog by caching frequent operations, reducing the weight of various theme files and providing transparent content delivery network integration. The goal is to improve the user experience for the readers of your blog without having to change WordPress, your theme, your plugins or how you produce your content. When fully utilized, your blog will be able to sustain extremely high traffic spikes without requiring hardware upgrades or removing features or functionality from your theme.
Features and benefits include:
- Improved progressive render (non-blocking CSS and JS embedding)
- Reduced HTTP Transactions, DNS lookups, reduced document load time
- Transparent content delivery network (CDN) support with automated media library import
- Bandwidth savings via Minify and HTTP compression (gzip / deflate) for HTML, CSS and JS
- Minification (concatenation, white space removal) of inline, external or 3rd party JS and CSS with scheduled updates
- Optional embedding of JS just above </body>
- Support for caching pages, posts, feeds, database objects, CSS, JS in memory with APC or memcached or both
- Caching of RSS/Atom Feeds (comments, page and site), URIs with query string variables (like search result pages), Database queries, Pages, Posts, CSS and JS
- Complete header management including Etags
- Increased web server concurrency and reduced resource consumption, increased scale
In essence, anything that can be automated to squeeze out every bit of server performance and minimize bandwidth utilization has been done, leaving your readers with an optimized user experience.
