What does Mod_PageSpeed do?

When you are online, all that matters is how fast your website loads and how easily visitors can access it. If your webpage takes anymore than 3-5 seconds to load, there is a strong possibility that visitors might close your website.

What can you do to make sure this doesn’t happen?

Introducing to you Google’s Mod_PageSpeed which helps you speed up your website, literally. PageSpeed speeds up your site and reduces page load time. This open-source webserver module automatically applies web performance best practices to pages and associated assets (CSS, JavaScript, images) without requiring that you modify your existing content or workflow.

How does PageSpeed work?

PageSpeed improves web page latency and bandwidth usage by changing the resources on that web page to implement web performance best practices. Each optimization is implemented as a custom filter in PageSpeed, which are executed when the HTTP server serves the website assets. Some filters simply alter the HTML content, and other filters change references to CSS, JavaScript, or images to point to more optimized versions.

PageSpeed comes with a set of core filters designed to safely optimize the content of your site without affecting the look or behavior of your site. In addition, it provides a number of more advanced filters which can be turned on by the site owner to gain higher performance improvements.

PageSpeed can be deployed and customized for individual web sites, as well as being used by large hosting providers and CDNs to help their users improve performance of their sites, lower the latency of their pages, and decrease bandwidth usage.

PageSpeed can also help boost your website’s SEO. Some of the ways it helps are –

1. Combining your CSS files, automatically

By enabling this option, you are telling mod_pagespeed to combine all your CSS files into one large CSS file. This is great from a speed standpoint because now instead of having to grab 20 different files and reading through all of them before displaying your site, the browser only has to grab one. Really handy, eh?

2. Get rid of the Whitespace in your HTML

Yes, it’s true. PageSpeed helps get rid of all the whitespace in your HTML. The effect is that you’ve got less content to deliver now so your page sizes are smaller. That means less time to download the file, which means a quicker load time. Browsers don’t care how neatly your HTML is written, so why should you? 😉

3. Making ‘Caching’ easier

Caching is hard to get, but mod_pagespeed helps you get that just right! t it only has to perform that transformation once. What’s more is that you can set certain areas or files of your site to not be cached so they’re optimized “on the fly.”

4. Optimizing your Images

This module has the ability to optimize the images used by your site for faster download and faster display. It recompresses the images and adjusts formats to the optimized format if necessary (e.g. non-animated GIFs to PNGs, JPEGs to Progressive JPEGs, etc.) and it resizes the images.

Mod_PageSpeed is easy to install and even easier to use. The resulting benefits are numerous and quite satisfactory. Have you tried using mod_pagespeed before? Give us your thoughts on it 🙂
