Vignette Delivers High-Performance Web Experiences

Unique Intelligent Caching Product Designed to Improve Site Response Times and Reduce IT Footprint

AUSTIN, Texas--(BUSINESS WIRE)--Expanding on its Web Experience Platform, Vignette (NASDAQ: VIGN) announced its new High-Performance Delivery (HPD) software will be publicly available on March 28, 2008. HPD delivers a unique caching technology that automatically tracks dependencies on publishing events or site changes and immediately updates the Web site cache when those changes occur. This enables organizations to deliver faster and richer user experiences while accelerating site performance and reducing IT costs.

“The benefits of HPD actually go beyond page response time and throughput”

“Our Web site is the primary communications channel to our global customers, so it’s important for us to deliver a personal and timely Web experience that’s fast and always available,” said Scott Lawson, IT business systems architect at QAD, a leading provider of enterprise applications for global manufacturing companies. “Vignette High Performance Delivery can help us demonstrate that delivering fresh, dynamic content and maintaining a high-performance Web site are not mutually exclusive ideals.”

Unlike existing caching technologies that rely on time expirations and user interaction to regenerate cached items, Vignette HPD automatically invalidates and updates the Web site cache as changes occur. HPD’s approach helps ensure content changes across multiple Web pages are uniformly updated and available to site visitors in real time, dramatically reducing maintenance costs and virtually eliminating the risk of errors or missing content. Additionally, HPD’s straightforward setup and management can significantly reduce the amount of IT resources and infrastructure required to run a Web site.

Benchmark test results performed by Vignette in its performance lab showed Vignette HPD provides dramatic performance improvements under a variety of conditions. For example, in several tests performed by Vignette, when 80 percent of a site’s Web pages were cached, HPD provided a 450-500 percent improvement in peak sustainable throughput versus a site not running HPD. In these same tests, when 90 percent of the tested site’s Web pages were cached, the throughput improvement often exceeded 800 percent. Test results also showed significant performance improvements for sites running dynamic portlets using AJAX and SSI (Server Side Include) technologies. ¹

“The benefits of HPD actually go beyond page response time and throughput,” said David O’Connell senior analyst at Nucleus Research. “HPD can be used by a business analyst or even someone without a technological background in the line of business group. This enables companies to save money by off-loading tactical work from IT. More importantly, it gives line of business people more agility and independence in continually fine tuning their Web presence and adapting to business opportunities.”

“Some of the world’s most well-known brands rely on Vignette to help them deliver personal, social and multichannel Web experiences to their key audiences,” said Mike Aviles, president and CEO of Vignette. “By offering a product that can enhance the speed and reliability of those experiences, we are helping our customers improve brand loyalty, reduce their IT costs and better execute their unique Web strategies.”
