In a battle-hardened code base, all normal bugs were fixed - those that remain are usually quite bizarre. This is a story of one such bug and how it uncovered a less than optimal implementation in the JDK itself.
Continuous Profiling is a powerful and under-utilised technique for helping teams understand what their code is actually doing in production. If you want to know how to eliminate performance bottlenecks, save costs and recover from performance regressions quickly then this article covers the what, why and how on Continuous Profiling.
Founders Richard and Sadiq give a tutorial on Continuous Profiling in Java at the Virtual Java User Group. Find out how profiling in production can uncover performance bottlenecks, aid scalability and reduce your costs.
Production is everything. If your software doesn’t perform in production, it doesn’t perform. Thankfully there’s a range of information that you can measure and monitor that helps you understand your production system and solve any issues that may arise. But where do you start and what should you monitor and measure? What are the tradeoffs between different approaches?
Java 11 features a new Garbage Collector, the Z Garbage Collector (ZGC), which is designed for very low pause times on huge multi-terabyte heaps. In this article we'll cover the motivation for a new GC, a technical overview and some of the really exciting possibilities ZGC opens up.
Time waits for no one, but it will wait for a thread. This blog post can help you solve performance problems more easily by describing the different types of information that you can get out of an execution profiler, why they matter and how you can use them.
How we're helping to nudge people into systems thinking rather than just looking at narrow profiling views
Introducing Opsian's new Flame Graphs; how they work and how to use them to diagnose performance bottlenecks.
Java 10 includes a bunch of useful features that will make running the JVM in a container less painful
Java 10 contains a pretty big change when it comes to the G1 Garbage Collector, and it's an improvement
