Six months of highly-focused performance tuning results in DotNetNuke® version 4.4, an application twice as responsive as its predecessor, and with significant extensibility enhancements.

Seattle, WA, January 28, 2007 -- DotNetNuke® Corporation ( http://dotnetnuke.com ) today strengthened its position as the world's most popular open source web application framework for the Microsoft ASP.NET platform, with the general release of a significantly optimized product offering. Based on mature and robust Microsoft .NET technologies, DotNetNuke® 4.4 adds superior performance and scalability to its distinguished list of application features.

"Exceptional performance and scalability is a fundamental requirement of any enterprise software platform," said Shaun Walker, DotNetNuke® Corporation Co-Founder and CEO. "I am very proud of the framework optimizations we were able to achieve in our most recent release cycle. By focusing on the extreme challenges and constraints of a shared hosting environment we were able to deliver superior performance improvements for all stakeholder scenarios. These optimizations would not have been possible without assistance from Microsoft and I am extremely grateful of their ongoing commitment to the DotNetNuke® project and community."

Thousands of organizations worldwide rely on the DotNetNuke® web application framework for delivering their web, intranet, and extranet solutions. Ensuring that the platform provides exceptional performance and scalability in a variety of environments is crucial to customer satisfaction. DotNetNuke® 4.4 is the result of six months of highly focused performance tuning where the application was repeatedly load-tested, analyzed, and refactored to produce a highly optimized and efficient core engine. Preliminary results indicate that the application is twice as responsive and consumes half the memory of previous versions. With a simple upgrade path, the benefits of the latest release are readily available to both existing and new customers.

"DotNetNuke® 4.4 has increased base performance while significantly reducing the amount of memory usage each installation consumes," says Robert Cichon, President of CrystalTech Web Hosting, Inc. "Apart from the benefits we see server-side, this performance increase offers a significant reduction in page load times, which translates to more visitors staying on an end-user's site."

DotNetNuke® 4.4 also includes some new extensibility enhancements in terms of its modular software architecture, providing a more stream-lined and flexible default installation and tighter integration with the commercial plug-in ecosystem.

"We've been amazed at the performance increase in DotNetNuke® 4.4," said Tony Valenti of PowerDNN. "Installations now happen in 10% of the time and the new module installation system greatly reduces application startup time as well."
