August 14, 2000 PRESS RELEASE: "NORFOLK, Va, August 14, 2000--PostgreSQL, a leading open source database, routed the competition in recent benchmark testing, topping the proprietary database leaders in industry-standard transaction-processing tests. PostgreSQL, also known as 'Postgres,' is an object-relational database management system (DBMS) that newly formed Great Bridge LLC will professionally market, service and support. Postgres also consistently outperformed open source competitors, including MySQL and Interbase, in the benchmark tests. Great Bridge will market Postgres-based open source solutions as a highly reliable and lower cost option for businesses seeking an alternative to proprietary databases." "On the ANSI SQL Standard Scalable And Portable (AS3AP) benchmark, a rudimentary information retrieval test that measures raw speed and scalability, Postgres performed an average of four to five times faster than every other database tested, including two major proprietary DBMS packages, the MySQL open source database, and Interbase, a formerly proprietary product which was recently made open source by Inprise/Borland." "In the Transaction Processing Council's TPC-C test, which simulates a real-world online transaction processing (OLTP) environment, Postgres consistently matched the performance of the two leading proprietary database applications. The two industry leaders cannot be mentioned by name because their restrictive licensing agreements prohibit anyone who buys their closed source products from publishing their company names in benchmark testing results without the companies' prior approval." "'The test results show that Postgres is a robust, well-built product that must be considered in the same category as enterprise-level competition,' said Robert Gilbert, Great Bridge President and CEO. 'Look at the trendlines in the AS3AP test: Postgres, like the proprietary leaders, kept a relatively consistent output level all the way up to 100 concurrent users--and that output was four to five times faster than the proprietary products. Interbase and MySQL fell apart under heavy usage. That's a strong affirmation that Postgres today is a viable alternative to the market-leading proprietary databases in terms of performance and scalability--and the clear leader among open source databases.'" "The tests were conducted by Xperts Inc. of Richmond, Virginia, an independent technology solutions company, using Quest Software's Benchmark Factory application. Both the AS3AP and the TPC-C benchmarks simulated transactions by one to 100 simultaneous users in a client-server environment. One hundred concurrent users approximates the middle range of a traditional database user pool; many applications never see more than a few users on the system at any given time, while other more sophisticated enterprise platforms number concurrent users in the thousands. In a Web-based application, where the connection to the database is measured in milliseconds, 100 simultaneous users would represent a substantial load--the equivalent of 100 customers hitting the "submit" button on an order form at exactly the same time." "The AS3AP test measures raw database data retrieval power, showing an application's scalability, portability and ease of use and interpretation through the use of simple ANSI standard SQL queries. The TPC-C test simulates a warehouse distribution system, including order creation, customer payments, order status checking, delivery, and inventory management." "'What stood out for us was the consistent performance of Postgres, which stayed the same or tested better than those of the leading proprietary applications. Postgres performed consistently whether it was being used by one or 100 people,' said Richard Brosnahan, senior software developer at Xperts."
