Introduction to Java Performance Tuning

Introduction to JVM Tuning Training

The Introduction to Java Performance Tuning training course examines the philosophies, tools, and processes required to begin tuning a Java application.

Assuming most students have not experimented with performance tuning, the JVM Tuning training course begins with an introduction of performance tuning concepts, exploring what is and is not considered performance tuning.

To ensure a successful learning of tuning concepts, the Introduction to Java Performance tuning course also examines the Java platform and the Java Virtual Machine architecture. With the appropriate foundation laid, the course examines common tuning tools and their applications.

Course Summary

Tune a Java application to address system performance issues and crashes.
Advanced Java programmers and system administrators needing to increase Java performance by tuning their Java applications.
Skill Level: 
Learning Style: 

Hands-on training is customized, instructor-led training with an in-depth presentation of a technology and its concepts, featuring such topics as Java, OOAD, and Open Source.

Hands On help
3 Days
Productivity Objectives: 
  • Understand the performance tuning process
  • Establish performance characteristics and measurement strategies
  • Identify and determine potential causes for hot spots, areas of latency, and bottlenecks in your application
  • Design a performance tuning strategy for your application based on identified underperforming and established characteristics
  • Work with common tuning tools such as profilers, pstat, top, visual vm, etc.
  • Tune the JVM, including GC algorithms, memory profiles, etc.
Introduction to Java Performance Tuning is part of the Java SE Training curriculum.
All of our Java SE courses can be delivered using the IDE of your choice using either JDK 1.5, JDK1.6, JDK1.7 or JDK1.8 (Java 8).
