IBM S/390 Server Sets Web Performance Record


Select a topic or year


POUGHKEEPSIE, N.Y - 25 Jan 1999: -- IBM's S/390 G5 Server has set a new record for Internet performance, according to results of recent SPECweb96 testing. SPECweb96 is an industry-standardized benchmark for measuring Web-serving performance.

The 10-processor S/390 G5 Turbo server, running an early version of OS/390 Version 2 Release 7 with the IBM WebSphere Application Server, posted a rating of 21,591 hits per second -- a 50-percent increase over the previous SPECweb record. The WebSphere Application Server for OS/390 helps customers build a highly secure Internet presence. Contributing to the record-setting SPECweb performance was the improved TCP/IP performance technology -- the Fast Response Cache Accelerator -- in the eNetwork Communications Server, which is expected to be available with OS/390 V. 2 Rel.7 this March. The eNetwork Communications Server provides a high performance Internet protocol environment for customers with intense Web-serving needs. These SPECweb results show that companies engaged in e-business and e-commerce can benefit from the S/390 server's ability to handle large volumes of Internet and intranet business transactions. Customers also value the S/390 server's industry-leading scalability, availability, reliability and security.

"The ability to handle large volumes of requests is a critical factor for conducting transactions over the Internet," said Ross Mauri, vice president, solutions and strategy, S/390 Division. "This SPECweb benchmark shows that customers can use the most trusted server in the industry to conduct e-business, knowing that S/390 provides the most scalable Internet access throughput."

The IBM S/390 Parallel Enterprise Server - Generation 5 is the world's most powerful mainframe server available today. S/390 servers are used for mission-critical tasks ranging from recording airline reservations to running ATM networks for banks and using the Web for e-business and e-commerce.

SPECweb is among the world's most intensive TCP/IP benchmarks. It focuses on server performance by measuring the ability of the server to handle Web-site requests -- or connections. The frequency of connections challenges the system's ability to respond to large numbers of requests. The SPECweb benchmark measures the response time for each request and calculates a number based on overall throughput, expressed as maximum benchmark operations per second.

SPECweb was developed by the Standard Performance Evaluation Corporation's (SPEC) Open Systems Group -- a nonprofit organization -- in conjunction with leading research organizations and Web product vendors, including IBM.
