CACHÉ Post-Relational Database Exceeds 500,000 DBAPS

Cambridge, Mass.-September 15, 2003-InterSystems Corporation and HP (NYSE:HPQ) today announced results of a benchmark designed to test real-world performance and scalability of enterprise-wide healthcare systems.

The benchmark was a collaborative effort of the Cleveland Clinic, one of the most respected hospitals in the U.S. and consistently-ranked in U.S.News & World Report as one of America’s best hospitals, Epic Systems Corporation, supplier of the suite of applications used by the Cleveland Clinic, InterSystems Corporation, supplier of the CACHÉ post-relational database used to run Epic software, and HP, supplier of the servers used by the Cleveland Clinic.

The Cleveland Clinic, which currently has approximately 5000 concurrent Epic users, expects to more than double over the next few years. This test was designed to ensure that no bottlenecks would impede this aggressive growth plan. In order to make the results as accurate as possible, the benchmark used a full production version of the Epic software running a mix of electronic medical record, scheduling and registration users and operating on a realistic database.

Results Double Expectations, Scalability to Nearly 15,000 Users

The results significantly exceeded the initial benchmark parameters by handling 14,600 simulated users, while meeting stringent response time requirements. The tests were conducted on a 24-processor HP Superdome server with 128GB of memory running CACHÉ version 5. The database engine delivered sustained throughput of 540,000 database accesses per second (DBAPS).

According to Paul Grabscheid, InterSystems vice president of strategic planning, “With the rapidly growing sophistication of leading healthcare applications, plus expanding user populations as they are rolled out across the enterprise, platform and database vendors are under enormous performance pressure. Our aim, with every new release of CACHÉ, is to deliver measurably better performance and scalability. We test this continuously, not with artificial benchmarks, but with real-world applications such as Epic’s suite of applications. These results demonstrate that the latest version of CACHÉ 5 is meeting our performance commitment.”

“This benchmark included an IT topology where performance and scalability are critical in order to handle future demand. The platform tested represents not only the capabilities of today’s requirements for the Cleveland Clinic, but also provides price performance and growth for the Clinic for years to come,” said Paul Gerrard, Vice President of healthcare sales at HP. “The results are well beyond the current needs of most sites. Since this system allows for at least two more in-the-system upgrades, it certainly shows scalability to handle all of the growth a client might want to put on a single system.”
