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 organisations to deliver faster and richer user experiences while accelerating site performance and reducing IT costs.
“Our Website 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 Website 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 Website 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 Website.
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 per cent of a site’s Web pages were cached, HPD provided a 450-500 per cent improvement in peak sustainable throughput versus a site not running HPD. In these same tests, when 90 per cent 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. 
“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 multi-channel 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.”
 Testing was performed by Vignette personnel on Vignette systems in the Vignette Performance Laboratory in Austin, Texas. Actual results may vary depending on a broad range of implementation factors, including, but not limited to, hardware platform, software configuration, network parameters and system use patterns. You may not achieve the same or similar results or benefits even if you use the same or similar equipment and/or software applications.
