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.

Our 2021 Java Developer Productivity Report provides insights on the most popular Java technologies, including frameworks, application servers, JDK distributions, and more.Īlmost Half (46.6%) of Survey Respondents Use Multiple Java ProfilersĮarlier this year, we released our annual Developer Productivity report. Should I be using more than one Java profiler?.Which Java profiler tools find the highest number of bugs?.That's why in this blog we look at the top five java profilers, while answering the following questions: Even then, profiling a Java application can be difficult. When it comes to Java profilers, there are many on the market, and it’s often tough to determine what the differences are and which is best for your application. What works for other people may not work for you.
As with all problems which have many solutions, it can often be tricky to determine which is the best solution for you.
