Removes all comments, whitespaces, redundant and obsolete rules, which reduces the total number of bytes loadedД®xperimental filter which puts inlined javascript on an external resource. Minify External Javascript, Minify Internal Javascript This filter is applied only to javascript files smaller than the size set by sub-filter вЂњJsInlineMaxBytesвЂќ Inserts small external javascript filesвЂ™ content directly into HTML document, therefore reducing the number of requests. Increases the period of time in which cached javascript files are to be kept in local storage, preventing extra requests and data loading upon user return to the same webpageД¬reates the вЂњmapвЂќ between minified and original javascript files for improved readability during the debugging process This ensures that the loading of visible content is not interrupted Postpones loading and executing javascript files until a page is loaded. This potentially decreases the number of requests to servers in the future, since these libraries might be in user's browser cache from any other websitesД¬ombines multiple javascript files into one, therefore decreasing total number of requests by a browser

Replaces popular javascript libraries with remote latest free versions, from Google Hosted Libraries by default. These filters are applied to Javascript files, re-referring them to optimized files: Implements the same optimization as вЂњRewrite CSSвЂќ filter to all rules, declared under вЂњвЂќ attributes Additionally, this filter minifies all CSS. Replaces stylesheets with inlined CSS rules, containing only necessary rules for initial viewport, and defers the rest of CSS rules to be loaded after the page is fully loadedДЄllows other stylesheet and image related filters to be applied to local stylesheets. This filter will try to outline only stylesheets bigger than set by sub-filter вЂњCssOutlineMinBytesвЂќ The idea behind it is to create parallel connections to different servers rather than consecutive ones to the same host. Places stylesheets inclusion before any elements are introduced, which decreases the loading time by eliminating re-flows of a webpage Д®xperimental filter which puts inlined CSS rules on an external resource. Improves rendering of a webpage, leading to shorter loading times Rearranges the order of loading stylesheets and javascript files, assuring that scripts are not blocking CSS resources. Inserts any stylesheets, used by Google Font API, if they are smaller than a value, which is set by sub-filter вЂњCssInlineMaxBytesвЂќ This filter is applied only to stylesheets that are smaller than a size set by sub-filter вЂњCssInlineMaxBytesвЂќ Inserts small external stylesheet filesвЂ™ content directly into HTML document, therefore reducing number of requests. Mostly is used for proper work of later applied filters Transforms rules into corresponding вЂњвЂќ tags. This optimization is designed for reducing the number of requests by the web browser Replaces all rules with the contents of imported files, if the size of the affected stylesheet files is less than the number of pre-determined bytes set by the sub-filter вЂњCssFlattenMaxBytesвЂќ. Increases the time that cached CSS files are to be kept in local storage, preventing extra requests and data loading upon a user's return to the same webpage If a page requires several stylesheets, this filter combines them into one stylesheet, decreasing the number of requests to a web server These filters change CSS files to optimized versions through making them smaller, combining several into one or extending cache lifetime: They can be divided into five main categories: Pagespeed module filters are settings, based on which a webpage optimization rule is applied. Microsoft Internet Information Services - IIS WebSpeedв†ђ.Apache Traffic Server - ats_pagespeed.Other servers that offer a PageSpeed optimization module based on Google's PageSpeed SDK: Installation is relatively easy and can be done in two ways: from packages or build from source on the following supported platforms: Since PageSpeed module is an open-source library, it is frequently updated by numerous developers from all over the world and can be deployed by any individual sites, hosting providers, or CDNs. Each of 40+ filters corresponds to one of Google's web performance best practices rules. The largest advantage of these modules is that they do not require modifications to existing content or workflow, meaning that all internal optimizations and changes to files are made on the server side, presenting modified files directly to the user. The PageSpeed Modules are the open-source Apache HTTP Server or Nginx webservers modules, which automatically apply chosen filters to pages and associated assets, such as stylesheets, JavaScript, and HTML files, as well as to images and website cache requirements.
