Server-Level Full-Page Cache
Communicates directly with LiteSpeed Web Server to store static copies of dynamically-generated web pages.
- Faster page retrieval than uncached content
- Powerful cache-management tools that are impossible for the other plugins to replicate.
- Tag-based smart purging of the cache.
- Ability to cache multiple versions of generated content based on user agent, geography, currency and more.
Private Cache
Has the ability to cache personalized copies of a page, in situations where the content is pertinent only to the user who requests it.
- Pages that would publicly be uncacheable may be cached privately.
- Caching can be extended to include logged-in users.
Edge Side Includes (ESI)
ESI lets you "punch holes" in a cached page, and then fill those holes with differently-cached content.
- Large sites with rarely-changing content can be cached longer while punching holes for more frequently-changing widgets.
- Entire pages need not be cached privately if a hole can be punched for a personalized greeting or a shopping cart.
Image optimization
Reduces the size of your site's images in order to improve page load times.
- Facilitates the use of the WebP file format for even smaller image files.
- Individual images may be reverted back to their original formats if desired.
Crawler
Travels its way throughout the site, refreshing pages that have expired in the cache.
- Not reliant on external visitors to populate the cache.
- Minimizes the chances that a visitor will encounter uncached content
- Is smart enough to adjust its own level of resource consumption to minimize its impact on the server
CSS, JavaScript, or HTML Minification
Removes all unnecessary whitespace characters, newline characters, and comments from CSS, JavaScript, or HTML code
- Can be configured separately. Enable only the minification functions you need.
- Shrinks the size of the source code, making it more efficient to transmit over networks.
CSS and JavaScript Combination
Combines multiple JavaScript or CSS files into one.
- Can be configured separately. Enable only the combination functions you need.
- Reduces the number of requests made by the browser and potentially removes duplicate code, both of which translate to improvements in speed.
HTTP/2 Push
Anticipates the browser's needs and acts upon them without without waiting for a separate request.
- Sends the included CSS and JavaScript files when index.html is requested.
- Reduces the number of requests necessary when loading a web page.
Content Delivery Network Support
Complements the dynamic-page-caching functionality of LSCWP by facilitating the use of a CDN for static content.
- Eliminates the need for a separate CDN plugin.
- Content Delivery Network usage speeds up your site by serving static content to visitors from locations that are geographically closer to them.
Browser Cache Support
Facilitates storing static content locally on the user's device. Content is pulled from the device's local storage until the browser cache expires.
- Simple ON/OFF button. No complicated setup.
- No fussing with configuration files. LSCWP edits .htaccess for you.
- Eliminates the need for a separate Browser Cache plugin.
- Browser cache usage speeds up your site. No matter how fast the connection, displaying a local image will always use fewer resources than transferring an image across the internet.
Lazy Load Images
Loads images and iframes asynchronously.
- Saves time by loading only that media necessary to fill the current viewport.
- Load remaining images and iframes on an as-needed basis.
- Appeals to mobile visitors conscientious about the cost of bandwidth.
Database Optimization
Keeps the WordPress database slim, trim, and as efficient as possible.
- Speeds up database queries by eliminating the clutter that accumulates over time.
- Eliminates the need for a separate database optimization plugin.
