SIMD Vectors in the HotSpot JVM - Auto Vectorization and the Vector API<p>Explore the latest work on the HotSpot JVM, with a focus on auto-vectorization and the Vector API.</p>
Read MoreZGC: A Decade of Redefining Java Performance
<p>ZGC is a concurrent garbage collector, meaning all heavy GC tasks are performed alongside application threads, resulting in sub-millisecond pause times. This talk will explore a brief history of ZGC, its internal mechanisms, the performance in JDK 25, and future development plans.</p>
Read MoreEpisode 60 “How JEPs Drive Java's Evolution” [AtA]
<p>JEPs are OpenJDK's vehicle for documenting and communicating substantial changes of the Java language, its APIs, and the runtime but also the JDK project itself.</p>
Read MoreBetter Tools for Immutable Data
<p>This session covers new and upcoming Java features for working with immutable data, and explains how they improve reliability and performance while enabling JVM optimizations and guiding when to use them.</p>
Read MoreCan Java Microservices Be As Fast As Go? A 2026 Benchmark Update
<p>Six years after first comparing Java and Go microservices, the authors revisit the performance question: whether carefully implemented Java and Go HTTP services still deliver similar results on modern runtimes and hardware. Rather than framing it as a language competition, the 2026 article examines how each performs as payload sizes and concurrency increase, with all code, benchmarks, and results available in a companion repository.</p>
Read MoreHow Agentic Coding Can Help You Migrate Java Applications Faster
<p>Learn how agentic coding transforms Java migrations by acting as an intelligent development partner.</p>
Read MoreSimplifying Weak Reference Processing in ZGC
<p>What are GC barriers and how do they relate to ahead-of-time compilation? This blog post explores the intersection of HotSpot's GCs and compilers through the lense of implementing GC-agnostic load barriers at the assembly level, and gives key insights on performance and overall takeaways.</p>
Read MoreExploiting GPU Tensor Cores from Java using Babylon
<p>this article shows an approach to extend the HAT programming model with an API for explicit tensor-core programming. Furthermore, it shows how to make this approach generic to be able to process computations expressed with the proposed HAT tensor core API on accelerators without explicit tensor instructions.</p>
Read MorePerformance Improvements in JDK 26
<p> To give you a clearer view of the performance work happening across the Java platform, this article highlights a selection of notable performance related improvements in JDK 26, grouped into four major areas: JDK Libraries, Garbage Collectors, Compiler, and Runtime.</p>
