This article discusses the best known methods for tuning the performance of the BEA WebLogic application server running the SPECjAppServer2002 benchmark on Intel architecture platforms. We describe a top-down, data-driven, and closed-loop approach to performance tuning, and touch on key advantages of BEA WebLogic that improve the performance of J2EE workloads. Introduction Java has become increasingly important in server-based applications. Consequently, standardized, robust, and scalable application support frameworks have become critical. Java 2 Enterprise Edition (J2EE) addresses this need, providing a comprehensive specification for application servers, including componentized object models and life cycles, database access, security, transactional integrity, and safe multithreading. One such application server is the BEA WebLogic application server. SPECjAppServe... (more)

WebSphere vs WebLogic: IBM and BEA Spar Over SPEC Results

Benchmarks can mean whatever you want them to mean, it has always seemed. Although useful as a rough guide to performance, and sometimes price/performance, technology companies are famous for interpreting complex benchmark results as victories over their competition and them employing visual aids such as planes, snails, and automobiles to demonstrate their point. The latest benchmark brouhaha may be over the newly developed SPECjAppServer2004 benchmark from SPEC (the Warrenton, VA-based Standard Performance Evaluation Corp.) This benchmark is the latest in the "Java Client/Server" category, and replaces SPECjAppServer 2002, which has now been retired. It "is designed to measure the performance of J2EE 1.3 application servers, (and) includes an enhanced workload by adding a web tier, JMS, and other changes to SPECjAppServer2002," according to SPEC. And it has lent ... (more)

VMWare Develops Enterprise Virtualization Benchmark

VMware has developed VMmark, what it calls "the industry's first benchmark system providing customers and partners with a robust, reliable way to measure the performance of applications running in virtualized environments." As part of VMware's effort to promote open standards in the industry, VMmark is the result of two years of engineering design, collaboration with partners, and review of extensive customer survey data in order to accurately represent customer environments. "With customers asking for ways to measure and compare performance on different server platforms, VMware worked closely with partners to design and implement VMmark," said Raghu Raghuram, vice president of product and solution marketing for VMware. "We created this open benchmark to enable customers to make the best decisions about running mission-critical applications on virtual infrastructure... (more)

CiRBA Version 4.6 Opens Up Cross-Platform Virtualization Opportunities

CiRBA announced the release of Version 4.6 of its virtualization and consolidation analysis software. With Version 4.6, CiRBA adds to its workload analysis, enabling organizations to plan and design virtualized infrastructure on any platform – including mainframes – according to workload personalities, risk tolerance, service level agreements and performance requirements. This advanced workload modeling also can consider the impact of iSCSI storage and network connectivity on virtualized servers to optimize placements and use of these technologies without impacting performance. Advanced Workload Benchmarking Each application has its own distinct workload personality that impacts how it will perform on any given virtualization platform and how well it fits with other resources on a server. Benchmarking is critical in determining how applications will per... (more)
