EAP6 performance Tuning
4 likes5,039 views
The document discusses performance tuning for JBoss EAP 6. It covers tuning the JVM, EAP 6 configuration, JDBC pools, EJB pools, web pools, and logging. It also discusses monitoring tools like JMX, VisualVM, JBoss Operations Network, profilers, thread dumps, and GC logging. The overall goal is to understand an application's requirements, instrument it, identify bottlenecks, and tune the various components and settings to optimize performance.

- 2. Agenda ● Performance Tuning – JVM Tuning – EAP6 Tuning (Web, EJB, JDBC, Logging etc.) – Monitoring Tools
- 3. Performance Tuning Principles ● Understand your Application performance requirements ● Plan for peaks, not averages ● Always instrument your application ● Understand where your application spends its time ● Replicate or model your production environment
- 4. JVM Tuning
- 5. JVM Tuning – Two types of GC
- 6. JVM Tuning – Basic Steps
- 7. JVM Tuning – Tune JVM Heap

- 13. JVM Tuning – Tune the GC algorithm
- 14. JVM Tuning – Serial Collector
- 15. JVM Tuning – Parallel collector
- 16. JVM Tuning – Concurrent Collector
- 17. JVM Tuning – G1(Garbage First) collector ● G1 is low pause, low latency Garbage Collector – One Large contiguous Heap Space split into fixed sized regions. – Intended to be a long term replacement of CMS – Officially supported as of 7u4, EAP 5.2 and EAP6. ● G1 is concurrent, Parallel and compacting – Concurrent for Refinement, Marking, cleanup – Parallel for STW pauses – On the Go Heap compaction ● Use When – Heaps Larger than 4GB – Faster and High performance over other GC Types with – Uses more memory and CPU than other GC types.
- 18. JVM Tuning – Other JVM Settings - Use Large Pages for Memory intensive application (-XX:+UseLargePages) - Server mode (- server) - AgressiveOpts ( -XX:+AggressiveOpts) - Thread Stack size (-Xss128k)
- 19. EAP6 Tuning 1. Tune Configuration 2. Tune JDBC pools 3. Tune EJB pools 4. Tune Web pools
- 20. EAP6 Configuration Tuning 1. Slim the Configuration - unused profiles - unused data-sources (for ex. ExampleDS, H2 Driver) - unused Subsystems (for ex. Mail, Messaging, Modcluster) 2. Separate Application logging from Server logging. 3. Deploy Using CLI 4. Turn off hot deployment scanner 5. Use Modules (database drivers, shared libraries etc.)

- 37. Software Patching ● Understand the needs and goals in your environment ● Use some sort of change control process or tool ● Apply patches on a "need only" basis ● Inspect and read all documentation regarding the patch ● Ensure consistency across all patch repository ● Testing ● Roll-back strategy ● Try not to get behind on patches
