"This was a real-world test of application performance in an Internet environment, and demonstrates the performance and scalability of the Java platform," said Doug Kaewert, vice president of market development and developer relations, Sun (SUNW).

The test was conducted using 1,000 concurrent users on a midrange Sun Enterprise E4500 server running Solaris at Sun's Garrison Laboratory in Burlington, Mass.

This test, according to a statement released by Sun, confirms the scalability of Java technology as an enterprise computing architecture and proves Windchill's readiness.

Windchill has been adopted by a number of major worldwide manufacturing enterprises to support the requirements inherent with having a large number of users.

Windchill is certified for the Java platform, version 1.1.7. One of the objectives of the tests was to quantify the performance and scalability improvements of Windchill on the Java 2 platform. Since Windchill is based on server side Java technology code, the Java Virtual Machine was also a key factor in testing Windchill performance.

This collaboration grew out of a long-term strategic relationship between Sun and Parametric (PMTC). The two companies have worked together on the Windchill application from its inception. A summary of the results, along with corresponding sizing guidelines, will be available from Sun later this quarter.
