Slow Java applications are a well-known problem in many projects: delays caused by ORM, complicated caching structures, and overloaded databases slow down performance. At JCON EUROPE 2025, the two-hour workshop “High-Performance Caching with Pure Java: Supercharge Your Sluggy Database Application” will show how to specifically solve these problems — exclusively with Core Java, without additional frameworks or cloud services.
Hands-on: Caching and Queries at Maximum Speed
Participants will learn how to develop a high-performance caching and query layer themselves — lean, memory-efficient, and directly in Java. The goal is to eliminate typical performance bottlenecks in database-based applications and increase system speed many times over.
The practice-oriented content includes:
- Build your own ultra-fast, memory-efficient cache—skip the complexity of multiple caching layers.
- Unlock microsecond query speeds—up to 1000x faster than typical JPA queries.
- Slash costs by reducing database load and expensive cloud service needs.
- Simplify your architecture—cut out the mess and focus on what really matters: speed and reliability.
- Apply a proven technique already used in production by companies demanding maximum performance with minimal infrastructure.
Expertise from the Head of the Open-Source Project
Florian Habermann, MicroStream’s CTO and expert in Java internals, leads the workshop. Habermann has over 20 years of experience developing high-performance Java solutions and has played a key role in projects like EclipseStore. He conveys how to leverage the JVM’s hidden performance potentials, specifically with immediate added value for your own projects and teams.
Anyone developing with Java should not miss this
The workshop is aimed at anyone who wants to sustainably improve the performance of their Java applications — without getting lost in complex technology stacks. The techniques taught can be directly applied to internal applications, business-critical systems, or performance-sensitive architectures.
