Informix Announces Highest TPC-C Performance Number on 32-Bit

INFORMIX ANNOUNCES HIGHEST TPC-C PERFORMANCE NUMBER ON 32-BIT SMP SYSTEM Silicon Graphics Selects Informix as Database of Choice for Its First TPC-C Benchmark MENLO PARK, Calif. (November 6, 1995) -- Informix Software Inc. (NASDAQ:IFMX), the leader in parallel processing database technology, today announced the highest-ever Transaction Processing Council TPC-C benchmark result for any 32-bit symmetric multiprocessing system (SMP). The benchmark, running INFORMIX=D2-OnLine Dynamic Server=99 version 7.1, the company=92s multithreaded, parallel processing database server, achieved a transaction rate of 6,313.78 transactions per minute (tpmC) on Silicon Graphic=D2=92s 16-processor CHALLENGE=D2 XL symmetric multiprocessing server with a price/performance ratio of $479 per tpmC. The result is the first TPC-C published on a Silicon Graphics SMP server, and represents 39% faster performance compared to Sybase=92s System 11 benchmark running on a SUN SPARCcenter 2000E server (4544 tpmC). The benchmark also represents a 12% faster transaction rate compared to Sybase= =92s most recent System 11 benchmark running on an HP 9000 Model T500 Corporate Business Server (5621 tpmC).* =93We are pleased that Silicon Graphics selected Informix as the database vendor to run its first TPC-C benchmark ever,=94 said Steve Sommer, vice president, Marketing, Informix. =93Silicon Graphics=92 decision to run on Informix reinforces the fact that Informix database servers are the number one choice of computer hardware manufacturers for publishing TPC benchmarks for systems based on the UNIX=D2 operating system. In just one benchmark, we nearly doubled the performance of our previous benchmark, and unlike our competitors, ran the benchmark on a product that is currently available to customers.=94 Informix leads the industry in TPC-C benchmark results with the most TPC-C results published to date using OnLine Dynamic Server (Informix- 25, Sybase- 11, Oracle- 3, All Others- 11).** Informix has been offering OnLine Dynamic Server, based on the company=92s parallel processing database technology Dynamic Scalable Architecture (DSA), since the end of 1993. DSA is widely acknowledged as the proven industry-leading database technology for performance, scalability and price/performance. The TPC-C benchmark test, developed in 1992 by the Transaction Processing Performance Council, is considered to be the best standard benchmark test for evaluating real-world application performance.=20 Silicon Graphics CHALLENGE servers are uniquely suited to meet the needs of users who are implementing large, complex database applications in the areas of OLTP, data warehousing, and data mining. Silicon Graphics=92 background= in visual computing and high-performance systems allows the company to deliver a client/server solution that is optimal for the visualization and analysis of data generated by OLTP applications. =09 About Informix Informix Software is the leading supplier of high performance, parallel processing database technology, for open systems. The company=92s database servers are the number one choice of computer hardware manufacturers for publishing Transaction Processing Council (TPC) benchmarks for UNIX-based systems. Informix products also include application=20 development tools for creating client/server production applications, decision support systems, and ad-hoc query interfaces, and connectivity software that allows information to be shared transparently from PCs to mainframes within the corporate computing environment. The company=92s corporate headquarters is in Menlo Park, California.
