Java Performance Tuning Workshop

JVM Tuning Workshop

The Java Performance Tuning Workshop training course covers the same content as the Java Performance Tuning Training course; however, it includes two additional days of customer application-specific tuning.

The Java Performance Tuning workshop examines the philosophies, tools, and processes to successfully tune a Java application. Assuming most students have not experimented with performance tuning, the course begins with an introduction of performance tuning, exploring what is and is not considered performance tuning. The general performance tuning discussion is made relevant through the examination of the Java platform and the Java Virtual Machine architecture. With the appropriate foundation laid, the course examines common tuning tools and their applications. The meat of the course is found in the performance tuning process discussion and is made practical through a hands-on examination of general tuning best practices and heap tuning.

Course Summary

Learn how to apply Java Performance Tuning practices to YOUR application.
Advanced Java programmers and system administrators needing to increase Java performance by tuning their Java applications.
Skill Level: 
Learning Style: 

Workshops are instructor-led lab-intensives focused on the practical application of technologies through the facilitation of a project-related lab. Workshops are just the opposite of Seminars. They deliver the highest level of knowledge transfer of any format. Think wide (breadth) and deep (depth).

Workshop help
5 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.
Java Performance Tuning Workshop 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).
