Performance Tuning
  • This is the course that you will have wished you had attended when your boss is breathing down your neck asking why the application is slow.
    Dr. Heinz Kabutz, Javaspecialists
  • The best course I ever attended: High knowledge of the trainer. Very helpful information, which could be used in real life.
    Rafal Zablocki, ING
  • Well balanced mix of theory, practice and real-life stories...it was probably the most useful professional training course I have ever attended.

Java Performance Workshop

Fast Java™ Fast

Overview

No tips, not tricks, just solid battle proven techniques to get to the bottom of any performance regression fast.

The workshop will provide you with a deep understanding of how the JVM works along with tooling needed to fully characterize performance regressions. You will work on exercises that contain real problems often seen in real production environments. Each exercises has been desinted to challenge your thinking. During the workshop you'll:

  1. know where to start an investigation
  2. gain familiarity with tools
  3. understanding which tool is best for each circumstance
  4. learn how to quickly identify the root causes of poor performance in your applications
  5. undertand how to find critical supportive evidence before deciding on a potentially expensive course of action
