Java Profiling tools

Instantly find and fix performance issues in your applications without affecting your overhead

A powerful low overhead alternative to free Java profiling tools

FusionReactor Ultimate is a powerful alternative to free Java profiling tools such as JConsole and VisualVM. By using FusionReactor, developers and DevOps teams can identify and troubleshoot bottlenecks in code without affecting the production environment. Using Java profiling tools can be an excellent way to troubleshoot Java applications with complex issues. From free Java profilers that come with the JDK to commercial software like YourKit, these tools range in price and functionality. Free Java profiling tools, however, come with a heavy overhead on the application. For any application in production, Java profilers introduce too much latency and overhead. With FusionReactor running in production with a <1.5% overhead, you don’t have to worry about impacting end users.
