The YourKit profiler is one of the most established leaders among JVM profiler tools. Oh, we’ll also give an honorable mention to XRebel, the performance tool for Java developers, taking over 3% of the votes, which wasn’t even a year old at the time the survey was released! We’ll look through our top 5 Java profiling tools in reverse order of usage for increased tension and suspense, even though you already know which is top!ĥ. Let’s take a look at them in a little more depth. You might want to use JMC in production, but XRebel in development as each tool is better suited to different environments. You might have a preferred tool for each of those tasks.

The job, however, may vary, for instance, you might be trying to find and fix specific types of IO issues or code bottleneck. This helps to show there is a right tool for the right job.
Well, from the graph below, you might be able to blame not having enough tools, as there’s a definite trend showing that you can find more performance issues if you use multiple tools. This may well be because it is designed to be used in development, a place where it’s easier to find and eliminate bugs. From our personal point of view, it was really exciting to see XRebel finding some of the most bugs out of any tool. Tools which did very well include JProfiler, XRebel (which is more than a profiler actually), NetBeans profiler, JMC, and JProbe. As such they would be able to find more performance bugs than others anyway. We might also be able to infer that if a team were able to write their own in-house performance tools, they are likely to be closer to the nirvana that is a performance expert. This might be because those who write the custom tools work with very particular applications and have the specific application knowledge to expose certain bugs that other tools may not. Most performance bugs were found by custom in-house JVM profiler tools. It turns out that it was very common for teams to use multiple tools when profiling a Java application, as each tool tends to be better in certain phases or the application lifecycle, or perhaps preferable when chasing down a particular type of performance bug. This time it’s because the question allowed for multiple choice answers, in case people tended to use more than one profiling tool on their applications. The reason for this isn’t basic math incompetence. The wily among you will have noticed that the first image in this blog contains percentages which do not add up to 100%. Java profiling is the dynamic analysis of the execution of a Java application, including memory utilization, speed and frequency of function calls, and more. The great news is we gave $0.50 for every completed survey to a great charity called Dogs for Good (formerly Dogs for the Disabled), which provide assistance dogs to disabled children. It was based off a performance survey which collected responses from over 1500 developers, testers, architects, and many more interestingly named job titles.
