4 Agenda What's New in Performance for V8.5 What's New in Performance for V.Next IBM Corporation

5 Disclaimer All Performance data presented in this presentation is gathered in a controlled environment. Your own test results may vary based on hardware, software or infrastructure differences All data is meant to be used as a guide IBM Corporation

6 Performance Analysis and Improvement Approach We focus on a blend of complete system benchmarks and micro benchmarks to isolate specific customer scenarios Test on a blend of hardware platforms and OS levels We cover all current hardware platforms to ensure performance Drive to answer architectural issues and performance impacts of specific OS We study the important aspects of performance to your business New programmatic APIs ability to deliver on promise Throughput and response time of the server under different loads Resource utilization (CPU, memory, disk, network, etc) Effect of adding processor (SMP/Vertical scaling) Effect of adding nodes to a cluster (Horizontal scaling) But we can t cover everything Over 1000 different hardware and OS combinations are supported by WebSphere Application Server IBM Corporation

7 SPECjEnterprise 2010 Benchmark Architecture Based on JEE 5.0 specifications Includes broad programming model coverage EJB 3 JPA managed CMPs JMS and Message Driven Beans Stateful and Stateless Session Web container, Servlets and JSPs Web Services Currently replace 50% of RMI interactions WS Wrapped EJB as well as servlet based WS Simple inline calls as well as complex binary inline and MTOM messaging Transaction management Database connectivity Example of development best practices Efficient and highly analyzed design, based on MVC (Model / View / Controller) architecture. Pedigree Jointly designed by the world s leading application server development teams All code was designed, developed and reviewed by IBM, Oracle, SAP, RedHat, and others IBM Corporation

8 DayTrader Benchmark Simulates an online stock trading application. Matches Java EE 5 specifications using JPA Entities and EJB 3.0 Session Beans Focuses on core Java EE technologies including Servlets, JSPs, JDBC, JMS, and EJBs (Stateless Session, CMP Entities, and MDBs) Run primarily in two modes: JDBC Direct Servlets make JDBC calls directly to the Database. Full EJB Servlets drive load to Session Beans and Entities to the Database. Serves as the basis for other performance scenarios including security, scalability, etc IBM Corporation

9 DayTrader 3 Benchmark Servlet and DMAP caching Cache data in various places in design (since most account/profile info will not change) Can use REST-based URL caching for Web 2.0 UI and/or JAX-RS interfaces Config stored in DB and cached on servers User local calls between SLSBs to run workload in single JVM Split modules out onto separate servers using WS, JAX-RS, JMS for inter-module communication and link up via config More modules (jars, wars, etc.) Better stressing of application deploy, etc IBM Corporation

10 SOABench Benchmark An end-to-end cross-product benchmark for SOA foundation products. This report focuses on the facet stressing Web services performance. Models an auto insurance claim handling application. Payloads based on customer representative data containing a mix of all schema types Uses JAX-WS web services adhering to the Java EE5 spec. Qualities of Service such as Addressing and Reliable Messaging are used IBM Corporation

11 Messaging Overview and Benchmark for JMS JMSPrimitives application suite used to measure the performance of J2EE based messaging scenarios Designed to stress the messaging component of WebSphere Application Server Report covers the performance of the default messaging provider, focusing on JMS and Message Driven Beans. Messages consumed by an MDB bound against queue/topic Provides ability to measure peak message throughput for various messaging configurations: Filestore & datastore Persistence & Non-persistence Point-to-Point (PtP) and Publish Subscribe (PubSub) IBM Corporation
