Radware’s FastView™ for Web Performance Optimization

Companies like Visa, Wine.com, and Petco rely on FastView to speed up their websites and enterprise applications.

Eighty percent of performance issues happen at the front end, at the browser level.

That’s why the key to faster websites and web-based applications is to improve front-end

performance – optimizing each page’s code so that pages render faster in the browser. In

the past, front-end optimization (FEO) was time consuming and could only be performed

manually by developers with specific performance expertise. Radware’s FastView

transforms FEO from a lengthy and complex coding process to an automated function

performed in real time, accelerating web application response time out-of-the-box.

FastView: Industry-Leading Web Performance Optimization Solution There are dozens of best practices and rules for optimizing web performance. FastView automatically applies these performance rules across your website or web application, delivering faster page-load times immediately. The results: happier users, increased conversions, higher revenues, improved search engine results, and more productive employees. In addition, your development team can return to focusing on building new features rather than endlessly optimizing your website’s code.

Solving 4 Critical Performance BottlenecksRadware’s FastView solution employs a unique and holistic approach to accelerating web applications by solving various performance bottlenecks. Here are 4 examples:

1. Simplifying large, complex web pages. The average web page is a staggering 965k and contains 85 objects. This means that it takes dozens of requests to the server to retrieve the page’s content, making the overall page load time slower. Though there are many coding best practices for reducing the number of server roundtrips and making pages smaller, implementing these best practices is a never-ending task. FastView automatically applies these best practices across your website or web application, making each page as fast as possible.

2. Predicting where your visitors are likely to go. FastView preloads the relevant page elements in the browser to have them on standby resulting in faster repeat page load time. FastView constantly learns how your visitors use your site in order to detect hot pages (i.e. pages through which people often access the site) and predicts what pages people are most likely to want to see next. FastView serves those hot pages faster by using advanced

techniques that optimize repeat views, and accelerates targeted page flows by preloading the objects for these pages to the visitor’s browser, before the visitor clicks to see the next page. And when the visitor does click, the result is instantaneous page load.

3. Third-Party timing and SLAs. Embedding third-party scripts (such as ads and social media widgets or analytics tags) in a page is an inherent performance problem. Many third-party snippets block the page from rendering until after the third-party content has loaded, adding entire seconds to a page’s total load time. FastView allows you to retrieve third-party content in parallel as well as create third-party service level agreements (SLA) that allot a maximum wait time for each third-party script on a page. If the script has not loaded within this time frame, it is deferred until after the rest of the page renders and/or cancelled altogether.

4. Recognizing that not all browsers are created equal. Each browser type has its own preference as to how it renders pages, how many connections are opened, etc. Techniques that work for one browser type can slow down, or even break, pages in a different browser. FastView creates custom optimization templates for each browser, making pages load in the most efficient way possible on each browser type.

Best Acceleration for Mobile Clients and the Mobile WorkforceWhen it comes to mobile clients, many of the performance problems that plague desktop clients still apply. However, there are inherent characteristics in mobile clients that make the application acceleration treatments different. For instance, a traditional browser cache in mobile clients is quite limited in size, making traditional browser caching difficult and ineffective. As a result, FastView uses the scaffolding of HTML5 local storage to offer a mobile browser cache that is comparable to the desktop browser cache. Mobile Super Cache, enabled through Radware’s FastView solution, offers site owners the ability to configure persistent, reliable storage for caching objects from their site on mobile devices, enabling significant acceleration also for mobile users.

As well, the form factor of mobile platforms presents new opportunities for acceleration that enhance certain techniques. For example, image compression can be applied based on the characteristics of a handheld device; while degrees of variance can also be applied based on whether the device is a phone or a tablet.

FastView offers web application owners several additional web performance acceleration capabilities which are optimized for mobile clients and browsers and also include touch-to-click conversion and eliminating mobile redirects.

FastView + ADC + CDN = Maximum AccelerationYou may already be using an Application Delivery Controller (ADC) to better load balance application traffic and offload servers and a content delivery network (CDN) to store content closer to visitors, shortening the distance it has to travel. But neither ADCs nor CDNs reduce the number of requests required to render each page and they have no effect on browser efficiency. FastView picks up where the ADC and CDN leave off, transforming the content itself so that it renders as quickly as possible in the browser.

The chart below illustrates a typical implementation of FastView alongside a CDN and an Application Delivery Controller (ADC). Note that while the CDN/ADC solution reduced load time by approximately a third, it did not affect the number of server requests or the total payload. With FastView, the number of server requests decreased from 63 to 9, and payload was reduced from 769Kb to 456Kb. Most important, load time dropped to 2.8s, a 71% improvement.
