“As businesses rely more than ever on applications, application performance management has become a top operational priority; performance delays of just two seconds can cause a revenue loss of 4 percent,” said Alois Reitbauer, co-author and dynaTrace technology strategist. “As interest in application performance grows, more people want to further their careers in this field. Our eBook provides a pragmatic reference for those who are passionate about application performance and accountable for improving it.”

All key topics covered in Java Enterprise Performance — from application performance concepts and memory management to hot issues such as cloud, virtualization and more — will empower architects, developers, test and operations teams to understand, measure and optimize the performance of Java-based technologies and meet the challenges they currently face in complex enterprise environments. The eBook is being published online with new chapters added monthly.

The first two chapters are available today:
* Chapter One — Application Performance Concepts: considers how to become performance experts. Besides technical expertise, IT leaders need a solid understanding of how performance and scalability works. The chapter reviews how to collect and interpret data properly and which performance data is needed in a variety of use cases.
* Chapter Two — Memory Management: addresses the fact that memory management is often a major contributor to application performance problems. It highlights the inner workings of memory management and garbage collection to help understand memory-related performance problems such as memory leaks or excessive garbage collection, where they come from and how to optimize applications accordingly.
