Java Performance Tuning
Overview

This course provides the process of performance tuning Java systems and eliminates all types of performance problems, including planning for performance, building a performance testing and tuning environment, tools, tuning methodology and an overview of how performance is affected by the runtime Java environment. This course is essential in understanding how to most effectively tune any Java application.

Prerequisites

Those with a basic understanding of object oriented systems and Java.


Audience

This course is designed for Administrators, QA team members, developers, architects, consultants, IT specialists.

What you will learn

After completing this course, the student should be able to:

  • Describe the  plan for performance management of the project
  • Described when performance tuning will be required
  • Tune the heap spaces and garbage collection for optimal performance
  • Talks about minimize object creation
  • To build a performance tuning environment and profiling
  • How to use threads effectively
  • Tuning JDBC
  • Describe the I/O performance tuning
  • How to understand which aspects of performance tuning are affected by various project phases and components
  • Teaches you to work efficiently and effectively, resulting in code that is robust, maintainable, and fast
