Google PageSpeed Service Updated, So It Never Takes Long To Load

Google PageSpeed, the service that accelerates web browsing had a beta release last year. To use it, one must sign up and provide Google with the DNS entry, after which the service fetches the content from the server and re-writes it by applying best web performance practices. The fetched content is then made available to the end users via Google servers. The increased speed depends on various factors such as content on the page, browser used or location of access. Being a beta release, the service is available to a few webmasters and is free of any charges. Though, once the test period is over, the service is expected to be fairly priced.

Considering the scope of development available for the PageSpeed Service, Google has come up with it's improved version. It allows you to access a website at a rate faster than the previous version. This new version uses a re-writer called 'Cache and Prioritize Visible Content'. The re-writer improves the functionality by 'Caching HTML'. HTML is usually not cached because of personalized content. But the new re-writer caches the non-personalised content leaving the non-cacheable (personalised) part. Thus, Google Server needs to access the original site only to get the non-cached content while the cached part is already visible to the user. Additionally, it prioritizes the visible content which displays the available content directly on the screen, before waiting for the hidden text and photos to be fetched. Lastly. 'Javascript is deferred' until the page is loaded, as it is not required as early as the page content. These new additions in the technique are expected to considerably improve the web access speed.
