Performance analysis and tuning is often treated as an issue of subordinate importance until eventually in one of the final project phases the developers attempt to verify that their implementation meets the performance requirements.  Typically, a performance tuning is necessary to meet the goals. 

Potential performance issues to be addresses in this phase include memory management and garbage collection: 

The workshop explains the above mentioned aspects of performance tuning. Attendants will explore tools for analysis of memory consumption and garbage collection. They will learn and practice strategies and tactics for profiling and tuning of both their program and the JVM's garbage collector.  As JVM tuning is JVM specific, the workshop's focus is on one particular JVM: the HotSpot JVM developed by Sun Microsystems.

The workshop aims to provide sound knowledge tailored to professional programmers in an industrial context.  The workshop does not only present theoretical background knowledge.  Instead the focus is on gaining practical experience.  For this reason, a substantial part of the workshop consists of hands-on labs.

Attendants will learn how profiling tools work, how they help, where they fail, what they deliver and display, and how their results are best interpreted and used.  Among other things, attendants will practice how to use profiling tools to detect memory allocation hot spots and memory leaks, how to tune and how to verify the success of their tuning.

.

This is a course for Java programmers responsible for performance analysis and tuning and devopers interested in memory management and garbage collections issues.

The course is designed to build on existing expertise as Java programmers and aims to take the skills one step further. Prerequisite for the seminars is sound knowledge of Java and basic understanding of the virtual machine. 

OBJECTIVES

	Learn how to work with profiling tools
	Know how to track down memory leaks
	Practice how to identify and eliminate allocation hot spots
	Understand garbage collection
	Know your tuning options

The course is designed by Klaus Kreft & Angelika Langer and backed by years of experience in teaching  Java related topics and more than a decade of real-world experience in industrial software development in Java.

Angelika Langer is a freelance trainer/mentor in the area of object-oriented software development in C++ and Java. She is a recognized author and speaker at conferences worldwide and author of the Java Generics FAQ .

Klaus Kreft is a senior consultant for more than 20 years and has served as the lead architect on several successful industry projects. He develops in Java since 1995. He is a regular speaker at OO conferences in Germany.

Together they are authors of the book "Standard C++ IOStreams and Locales" and numerous articles on C++ and Java topics in various computer magazines worldwide, including the column "Effective Java" in the German JavaMagazin.
