Stop Struggling With Your Slow Persistence Layer And Finally Unlock Hibernate’s Best Performance!

Lots of developers struggle with Hibernate performance problems. Changes that worked perfectly fine on the test system break the performance of the production system. Their users complain about slow response times, and their database administrators blame them for executing too many or inefficient queries.

In most cases, they don’t even know why Hibernate executes so many queries or how they could improve them. They then try to solve these issues by copying code snippets from Stack Overflow, hoping that it solves their problems without introducing new ones. All of this causes stress and frustration and is often the reason for overtime and missed deadlines.

What if I told you that this doesn't have to be the case?

What if I told you that Hibernate includes lots of performance optimizations and that you can use them to implement high-performance persistence layers with ease?

What if I told you that knowing Hibernate's performance optimizations and advanced features are the key to finding and fixing performance problems before they cause trouble in production? This enables you to work on interesting tasks and you will be appreciated by your manager and team members as a true expert and at the same time, allowing you to spend your evenings and weekends with your friends and family.

For me, that has been the story of my career. My Hibernate expertise was one of the building blocks of my corporate career, and I’m now helping teams to optimize their persistence layers as a freelance consultant.

And I created the Hibernate Performance Tuning Workshop to share that knowledge with you.

Performance Problems Grow If You Don’t Fix Them Proactively

Most developers copy code snippets from Stack Overflow or create workarounds in their business code when they have to implement complex requirements with Hibernate. But for most of them, none of that works, because:

  • You are the only person who knows your application and the performance requirements of all use cases. Other developers, who don't have this information can't decide if a change will cause even bigger performance problems in another use case.
  • Copied code often causes unexpected side effects if you don't know how a feature works and when to use it. That’s especially the case if you don’t know how much the person who answered your question actually knows about Hibernate. In the worst case, the suggested mapping creates more issues than you already had and you will only recognize that after you have deployed your code to production.
  • You don't learn anything about Hibernate's performance pitfalls and optimizations if you just copy code from the internet. When you have to implement something similar again, you will not be any wiser, and you can't grow your expertise and career with this approach.

And what happens if you just do nothing? If you just keep doing what you’ve been doing?

You will pile up more and more problems hidden in your persistence layer, and your application will get slower and slower. 

You will spend more and more time fixing bugs and fighting performance problems instead of working on exciting new features. 

In the end, you will be stuck in a rut, working long evenings and weekends while your managers complain about the lousy performance of your code and the long development cycles.

How I Learned To Build
High-Performance Persistence Layers with Hibernate

I tried the same approach as you did. I copied code snippets from Stack Overflow and blog articles, only to find out that they didn’t work in my project, or that they caused other problems not mentioned in the articles.

The situation was frustrating, and I recognized that this approach wasn't working.

You need to really understand how Hibernate works and the performance impact each feature has so that you can choose the right one for your application. Otherwise, each decision comes down to pure luck. Sometimes your code will be lightning fast, and other times it will be horribly slow. To make it even worse, you often need to wait for your users to use your change until you know whether you made the right decision or whether it caused side effects you didn't find on your test system.

Years ago, I got fed up with this needless guessing game. I knew that other teams were using Hibernate to build high-performance persistence layers. There had to be a better way.

Stop Guessing, Make Educated Decisions!

I started to learn how Hibernate works internally and all the performance improving features it offers so that I could pick the right one for each use case.

Instead of copying random code snippets, I started to dive deeper and put a lot of effort into learning as much as I could about Hibernate. I read the documentation, the JPA specification, and various books, I participated in online and offline discussions and tried lots of things myself. 

After a while, all the previously disjointed bits of knowledge and understanding began to form a complete picture. One in which the different features started to work together and in which the subtle comments I found in some articles began to make sense:

  • I quickly began to understand why certain features improved the performance of some use cases but didn’t work that well for others.
  • As I gained a better understanding of Hibernate, implementing high-performance persistence layers became easier and easier. I avoided typical performance pitfalls and created maintainable mappings and queries, that performed amazingly well. 
  • As I learned about Hibernate and started to fix performance problems before our users found them in production, I also regained the enjoyment and fascination that I had felt when I first began to work as a software developer.
  • And I saw these same feelings when I shared my knowledge with my co-workers and showed them how easy Hibernate often makes it to fulfill high-performance requirements. Instead of being frustrated and blaming the framework, they used Hibernate with confidence and started to fix performance problems before they caused trouble in production.

Nowadays, I use the same knowledge to help teams all over the world as a freelance consultant, coach, and trainer. It’s always amazing to see how a better understanding of Hibernate helps you to avoid common performance problems and gets you one step closer to an enjoyable and successful career.

It Worked For These People, And It Will Work For You

Based on the insight I gained, I began to choose the optimal Hibernate feature for my use cases, to implement them with ease and enjoyment and to get recognition for my work.

But don't just take my word for it. Here is what other people say:

We doubled the performance of our services

I have been using Hibernate on and off for several years to supplement our custom Java database framework.


A year ago, we decided to migrate our monolithic application to microservices using JPA/Hibernate as the persistence framework. We have aggressive timelines so we needed to accelerate our knowledge of how to properly use hibernate so that our services would scale to meet the needs of our customers.

We discovered that using Hibernate was easy but, using it so that it scaled, required deeper knowledge. I came across Thoughts-On-Java while scouring the web for information on performance and pitfalls.

After subscribing to the newsletter, it became clear that Thorben has a firm grasp on the exact issues we were addressing. [...]

As a result of the training, we confidently refactored our code to follow the patterns described in the training course and doubled the performance of some of our services.

I recommend the training to anyone who wants their Hibernate applications to scale and to be maintainable in the future.
