Site Optimizer / Speedster

Note: This list is not an exhaustive list of features. Please try the demo to see this extension in action.

• Minify your Javascript, CSS, and HTML
  The Site Optimizer / Speedster reduces the size of your Javascript, CSS, and HTML using 1 of 4 minify technologies (JSMin, JSMin Plus, YUI Compressor, and Closure Compiler). These technologies work by removing comments, rewriting CSS statements in a more efficient manner, removing white space, and rewriting Javascript variables. This extension will even minify your inline JS / CSS. On a default Magento Commerce install, you can expect the following (as shown in the graph found in the product image gallery):

  • Javascript to be reduced from 112.7KB to 68.7KB (40% savings)
  • CSS to be reduced from 20.7KB to 16.6KB (120% savings)
  • HTML to be reduced from 51.4KB to 36.7KB (29% savings)
• Minify inline Javascript / CSS
  External CSS / JS is only half the story. The HTML and Javascript / CSS that are inside of each of your pages are equally important. Importantly, this data cannot be cached by the browser, so it must be downloaded on every page request. Other solutions completely ignore inline data.
• Intelligently combine Javascript / CSS files

  On a default Magento Commerce install, the number of Web server requests will be reduced by 16 (this number is usually even higher on a non-default install). This significantly reduces request latency and bandwidth and marginally reduces the HTML size of page. Also, it means your Web server will not have to work as hard which will allow you to server more requests per second.

  Do not compare the Site Optimizers / Speedsters ability to combine files with other modules. Other solutions that combine files will do so unintelligently, which actually increases total bandwidth. This is because the home page, the catalog page, and a product page will use different CSS / Javascript. For example, the product page uses the same Javascript / CSS as the home page, but with a few extra Javascript files. Other solutions will require the user to re-download duplicate Javascript / CSS when navigating from the home page to the product page. Our solution solves this problem.

• Compress your Javascript and CSS
  Your Javascript and CSS will be compressed using 3 different compression algorithms (gzip, gzdefalt, and gzcompress). All files are pre-compressed, so they are not compressed on a per-request basis. This reduces latency and CPU load and speeds up high traffic Web sites.
• Improve the browser cache management of Javascript / CSS files
  Every time your change your Javascript or CSS Site Optimizer will dynamically change the name of the files that the users see, we are able to tell their browser to cache the Javascript and CSS forever. This means that once downloaded, the user will never have to make another request for your Javascript and CSS. This reduces latency, bandwidth, and your server load.
• Optimize / compress image files for optimal performance ^New!
  The CSS / product images on your site will be highly optimized in order to reduce bandwidth and download time. Many sites have experienced 30%+ reduction in page weight as a result of image optimizations. The lower your page weight the faster your page will download, which means it will be loaded faster. This is especially important on todays wifi and mobile connections.
• Improve the browser cache management of images files
  Your catalog and CSS images will be rewritten and cached in a similar way as the Javascript and CSS. This means that once a user downloads an image, they never have to request that image on your server again. This can save dozens of server requests per page load and save hundreds of kilobytes per page load. On a default Magento Commerce install, this saves 20 web requests per page load just for the CSS images alone.
• Choose the minification algorithms that is best for your needs
  Different algorithmns have different characteristics and requirements. We don't limit your choice. We include them all so that your site can be optimized as much as possible.
