- prioritize_critical_css: Inline only the CSS used by the page.
- convert_to_webp_lossless: Re-compresses GIF and PNG images to lossless WebP.
- PageSpeed Console: The PageSpeed Console monitors your installation's performance and links to general information on how to improve the performance.
- Supporting downstream caches: Experimental feature for supporting caching proxy servers to allow HTML to be cached in these servers.
- Randomly drop expensive rewrites: To reduce processing load, PageSpeed can be configured to optimize the most frequently fetched resources, leaving infrequently fetched resources alone. This is accomplished by randomly dropping expensive (CSS and image) rewrites. Frequently fetched resources will have a higher probability of being rewritten than infrequently fetched resources. Over time, frequently accessed resources will be optimized and cached so a page will be fully optimized. Infrequently accessed pages will be left unoptimized or partially optimized, saving CPU time and cache space.
- DisableRewriteOnNoTransform: Default on, but may be turned off to allow PageSpeed to rewrite resources even if they have a Cache-Control: no-transform header.
- Experimental Shared Memory Metadata Cache: An in-memory cache that shares metadata entries between Apache processes on the same server. This can provide significant performance benefits.
- Client Options Header: Support for a new request header that can be used to configure image optimizations.
- Lossless & transparent WebP support: PageSpeed can now take advantage of support for lossless & transparent WebP images in some newer browsers, which can provide smaller file sizes than PNG.
- Embedding configuration into resource URLs: You can now configure PageSpeed to embed image & CSS optimization settings in resource URLs. This is useful in multi-server setups where perfectly replicating configuration information may be infeasible.
- Better CDN support in MapProxyDomain: You can now optionally provide a third argument to ModPagespeedMapProxyDomain in order to use a domains of a separate hosting site for optimized resources being proxied.
- IE6/IE7 support in lazy load images: The lazy load images filter now also applies for visitors using Internet Explorer versions 6 and 7.
- Support for HTTPS fetching
- Supports reloading all settings (including root settings) on the fly
- Now uses beaconing to determine content that should be prioritized (prioritize_critical_css, lazyload_images)
When dealing with websites hosted on multiple webservers, having a common cache backend for storing optimized assets make sense. Currently, IISpeed offers support for memcached to make that possible. A major benefit is that when webserver A has already crunched an image, webserver B can pull the optimized image from the memcached server, instead of having to redo the work.Lets take a look at how to get memcached up and running on Windows:You can get the memcached binary for windows here Extract the filesOpen a command prompt, head to the directory where you extraced memcached, a ....
WebP is a relatively new image format which can be used instead of the jpeg and png file formats. On average, image file size can be reduced by 30%-35% using WebP.IISpeed extends IIS with the capability to automatically rewrite images to WebP for browsers that support it (at the time of writing about 57%). For browsers that do not support WebP, images will still be optimized using the original file format. All these optimizations are performed on the fly when the webserver is delivering them, and don't have any impact on your workflow.Next to WebP transcoding ....
