Java Performance Tuning

Goals

This workshop provides a comprehensive introduction to tuning Java programs. It includes discussion of the basic memory model of Java, the HotSpot optimizing compiler, and Java profiling tools. It demonstrates ways to assess common performance problems such as excess memory and thread usage, and how to tune programs to perform better.

After completing this seminar, participants will:

Understand the Java memory and threading models and the HotSpot performance engine
Know how to use profiling and management tools to gather runtime information from applications
Be able to find and remove bottlenecks
Improve performance by tuning algorithms, memory usage, and thread management
Understand the Java Reference API
Tune specific language constructs and frameworks such as collections, distributed communication, JDBC, IO, and Swing.

Audience

Software developers with Java experience who wish to improve the performance of all types of Java programs.
