Java Performance Tuning Course

Learn practices and guidelines for highly performant Java applications

Overview

The course is designed to provide the skills and knowledge for optimizing Java applications for performance. It covers the fundamentals of performance tuning, including JVM internals, profiling techniques and common performance bottlenecks.

The participants (mainly Software Architects, Tech Leads and Developers) will learn a holistic approach to performance improvements, on the three major levels of any software application:

  • Infrastructure
  • Architecture
  • Code

Objectives

By the end of the course, the participants will:

  • Understand the performance aspects in a zoomed-out → zoomed-in approach
  • Understand the JVM architecture and its impact on performance
  • Optimize memory usage and the Garbage Collection process
  • Improve the performance of multi-threaded applications
  • Apply best practices for writing high-performance Java code
  • Optimize database interactions and I/O operations
  • Use profiling tools to identify performance bottlenecks

Duration and Schedule

The minimum course duration is 3 days, 6 or 7 hours per day.If possible, we highly recommend a longer duration, to allow more time for more hands-on work and for participants to troubleshoot their own Java projects (if possible).

Each course session will be composed of a theoretical and a practical part. The ratio between the theoretical and practical components will vary depending on:

  • The complexity of the discussed topic
  • The questions and discussions related to it
  • The participant's interest in that topic

Target Audience

This course is ideal for:

  • Java Software Architects, Tech Leads and Developers that want to understand & troubleshoot the application performance aspects in a holistic way
  • Java developers looking to enhance the performance of their applications
  • Professionals interested in understanding JVM internals and performance tuning techniques

Prerequisites

The course participants should:

  • Have a basic understanding of the deployment and scaling aspects of a modern Java application
  • Be proficient in Java programming
  • Have a basic understanding of JVM architecture and concepts
  • Be familiar with common Java development tools and environments

Testimonials

We really enjoyed Bogdan's training sessions. It's always cool to learn and have fun while doing them. He is very patient and always prepared to offer the best solution/explanation for any problem/question. ... I also love his ability to extend the context for each chapter, offering many smart hooks to integrate the concept in a broader picture, which makes it all easier to understand.

Sorin, Crossover

Bogdan is our coach who helped shape our vision to use Java and Spring/SpringBoot in today's marketplace. He is highly skilled, extremely passionate and has a strong work ethic. With his unique and practical approach, he taught us from technology fundamentals on up to software design and best practices. He is continuously helping us progress on a growing path in software development. I enjoy working with Bogdan very much and I consider him a friend.

Andrei, Óce

When we approached Bogdan for a Java training, our goal was to up-skill our team of PL/SQL developers in order to become proficient in Java. [...] Bogdan has vast experience in the topics and very good communication and presentation skills. The pace was very good and he was very thorough in responding all questions, providing lots of related documentation for further study.

Radu, Nokia

Working with Bogdan is really inspiring and I always learn something new from his training and coaching sessions. All the training sessions are well-structured, use examples and employ hands-on components. What I enjoyed most during his training sessions is that they made me eager to learn more and to extend my knowledge. And it's not hard to do, thanks to the documentation that Bogdan provides for further reading.

Corina, Cerner

For a year and a half I've participated in various courses held by Bogdan, from Java 8, Spring, Maven to Docker. He has a good methodology, a strong background, he keeps you interested and he is open for discussions even after the training sessions, which is very important. Usually we have more questions after we start using the knowledge from the courses.

Ion, Sociéte Générale

I have participated in several training sessions held by Bogdan, including Java 8, Maven, CI & CD, Git and Spring. Every time we were thrilled to discover the information and best practices described, especially as he exemplified them with many hands-on examples. Furthermore, there were a few things present in each session that defined Bogdan's approach, namely, professionalism, vast knowledge and experience, innovative solutions, a great personality and a sense of humor.

Lavinia, Elysian

I am the self-learning type; I usually get bored at every course/training, very quickly. With this course, it was not the case. I payed attention ~95% of the time, which is very rare for me.

Ionuț, Nokia

I was pleasantly surprised by this course, being probably much more than other courses that can be found online. The presentation is very good, the materials are well structured and prepared, with many examples. Moreover, I consider the context information to be welcome, some of it was not very "settled" for me, such as the information about the application architecture, etc. Another plus regarding the training and the trainer is the fact that I managed to pay attention approximately 99% of the time, which I find amazing.
