Java Performance Tuning
Practices and guidelines for high performance Java applications. Learn to identify bottlenecks, optimize JVM settings, and write code that performs well under load.
Overview
Performance issues can cripple enterprise applications, leading to poor user experience, increased infrastructure costs, and lost business opportunities. Understanding how to measure, analyze, and optimize Java application performance is a critical skill.
This course provides comprehensive coverage of Java performance tuning, from JVM internals to application-level optimizations. You will learn to use profiling tools, understand garbage collection strategies, optimize memory usage, and write efficient concurrent code. Through hands-on labs, you will gain practical experience diagnosing and resolving performance issues.
Objectives
The main objectives of the Java Performance Tuning course are:
- Understanding JVM architecture: memory model, class loading, and JIT compilation
- Mastering garbage collection: algorithms, tuning parameters, and GC log analysis
- Using profiling tools: JProfiler, VisualVM, Java Flight Recorder, and async-profiler
- Memory optimization: heap sizing, object allocation patterns, and memory leaks
- Concurrent programming optimization: thread pools, synchronization, and lock-free algorithms
- Database and I/O performance: connection pooling, caching strategies, and batch processing
- Benchmarking with JMH (Java Microbenchmark Harness)
Duration and Schedule
The standard course duration is 4 days, with 6 or 7 hours of teaching each day. Additional time can be arranged for analyzing your specific applications.
The scheduling per day:
- Day 1: JVM internals, memory model, and profiling tools introduction
- Day 2: Garbage collection deep-dive, tuning, and memory optimization
- Day 3: Concurrency optimization and database/I/O performance
- Day 4: Benchmarking, performance testing, and hands-on optimization workshop
