Measuring Application Server Performance using ECperf David Lucas President Lucas Software Engineering, Inc

Agenda Introduction ECperf Model Business Data ECperf & J2EE Servlet/JSP EJB ECperf Test Report Tuning Tips Conclusion

Introduction Welcome Benchmarks Why ECperf? What is ECperf?

Benchmarks What are they good for? Who uses them? Why would you use them?

Why ECperf? There was no easy way to compare EJB Containers for those who had never built EJBs. The ECperf was built through the Java Community Process to stress an EJB Container in the areas of performance and scalability

What is ECperf? "ECperf is a Enterprise JavaBeans(EJB) benchmark meant to measure the scalability and performance of J2EE servers and containers. " --TheServerSide The benchmark is geared at showing how a particular real world application will behave in a given EJB Container (middle tier).

ECperf - Business Model Customer Manufacturing Supplier Corporate

ECperf - Data Model Schema provided for major databases like DB2, Oracle, etc. There are a total of 22 tables Depending on database, some optimizations have been done as part of the ECperf Make sure you take advantage of your database performance guides

ECperf - Servlet/JSP Web based access to view, order and manage domains 14 JSPs 2 Major Servlets

ECperf - EJB Session Beans (about 26) Entity Beans (about 40) No Message Beans (see next spec)

ECperf - Deployment Standard/Distributed Client Simulator Server Database Supplier Simulator Manufacturing Simulator

ECperf - Test Build Sun's ECperf kit Vendor ECperf kit Configure environment properties and database Load database Descriptors Particular to your AppServer Deployment Particulart to your AppServer Execution database startup AppServer next client runner

DEMO This is a laptop! Please do not gage performance of anything on this machine. ;-) Quiz - How can I improve this test?

ECperf - Report What are BBops? Benchmark Business OPerationS They are measured per minute to represent a business transaction that completed through all domains. Certified results includes cost of system under test (SUT) / Bbops/min Type of Persistence Used

ECperf - Report Report must disclose: priced box containers ran on database type, OS, S/W, H/W and schema used software products used client box, OS, S/W, H/W network configuration

ECperf - Tuning Tips Run each domains tables on separate databases on separate machines Have a high troughput client driver machine Have high bandwidth between boxes Have a lot of memory and swap Have at least one EJB Container per CPU on a box Your results are good if Bbops/min is greater than (txRate*100)

Conclusion Benchmarks can be useful Run ECperf and compare for yourself in your environment tracks results, but be wise, they are not apples to apples. Future of ECperf (specjAppServ)
