This document discusses performance testing for service oriented architectures (SOA) and enterprise middleware. It covers typical server performance patterns like latency and throughput. It recommends establishing a clustered test environment that mirrors production. Open source tools for performance testing SOA are discussed, including Apache JMeter for load testing and soapUI for functional tests. The document also covers monitoring tools for analyzing performance.

Agenda
• SOA and Enterprise Middleware – Overview
• Typical Server Performance patterns
• Performance Test Environment
• Open Source Performance Testing tools – Apache Jmeter
• Open Source Performance Testing tools – soapUI
• Monitoring tools

3. Heading….
SOA and Enterprise Middleware
A Service Oriented Architecture is a set of components which can be invoked
and whose interface descriptions can be published and discovered

4. Heading…. of Performance Testing in SOA
Importance
• Higher level of integrations
• Reusable components
• Heterogeneous platforms
• Cloud complexities (auto-scaling etc..)

5. Heading….
Server Performance
• Latency – End-to-End processing time
• Throughput – The amount of messages server processes
during specific time interval

6. Heading….
Performance Testing Environment
• Clusetered setup identical to production environment
• Warm-up servers
• Initial Tuning
• Isolated Network
• Disable unnecessary server features – e.g:- DEBUG logs

7. Heading….
Performance Testing Environment
• Allocate enough memory for testing tool
• Tune open file limit in Linux
• Run clients from separate machines
• Avoid VMs (IO issues)
• Run testing tools in non-GUI mode
• Validate the stats given by tools by manual inspections

8. Heading….
Java Bench
• Java clone of AB (Apache Bench)
• Simple Performance comparison tool
• Lightweight tool without GUI

9. Heading….
Apache Jmeter
• Not a browser, no HTML rendering
• SOAP/XML-RPC and Webservice samplers for SOA
performance testing
• Data driven testing

10. Heading….
soapUI
• Easy-to-Use, open source web services testing tool
• Functional to Performance conversion in no-time
• WS-* support
• Pre-defined load test strategies

11. Heading…. Analysis and Monitoring
Performance
• Tools provided by OS (e.g:- top)
• Profiling Tools (e.g:- Jprofiler)
• Monitoring tools (e.g:- Jconsole with plugins)

12. Heading….
Q&A
