Google updates PageSpeed Service so you don't waste precious seconds waiting for pages to load
Last year, Google launched its PageSpeed Service, aiming to improve our experience across the web while reportedly deferring its own financial interests. The concept was sound -- similar services like Akamai work to accelerate web browsing by caching pages in much the same way -- but there's always room for improvement. The latest PageSpeed beta uses some straightforward techniques to improve performance even further, using a new rewriter called "Cache and Prioritize Visible Content." Using this new tool, your browser will load content that appears "above the fold" before fetching text and photos that would be initially hidden on the page, while also prioritizing other content ahead of Javascript, which often isn't needed as quickly as more basic elements. Finally, for pages that contain HTML that isn't cacheable, such as when personalized info is returned, standard portions of the site are cached and displayed immediately, while other content loads normally. The new tool isn't a perfect fit for every webpage, but we'll take a boost wherever we can get it.
Google wants to speed up your site, while resisting the urge to sell you stuff
Google has plenty of things going for it, but patience has never really been high on the list -- not surprising, really, for a company that employs scooters to get around the halls of its offices. The search giant has taken a similar approach to the web, offering up a number of services to help speed things up around the old tubes. Page Speed Service is the latest simply named initiative on that front, which has apparently offered up speed improvements of 25 to 60 percent in its early testing phases. How does this magical quickening work? Google grabs content from your servers, rewrites pages with performance best practices, and sends them out through its own servers. The service has raised a few eyebrows, but Google insists that Page Speed Service is all about improving performance, not collecting information for future advertising opportunities.
