If you are a developer, some point of time you will have to use JProfiler for measuring the performance of your application. Many times, this is left to specialized performance teams or developers who know the tools well, but don’t know much about the code that they are trying to measure the performance. This approach, despite might be working, can have its flaws. Especially since performance team members are not writing the code. So as part of this past, I want to debunk few myths around this and why a developer should equally focus on a tool like JProfiler to check the performance.
- The official JProfiler plugin for JProfiler by ej-technologies.
- JProfiler (Used by 25.7% of respondents) JProfiler is a comprehensive Java code profiling tool for Java SE and Java EE applications with plugins for all major IDEs which provides enhanced analysis of the collected profile data. As with any profiler, the CPU profiling is perhaps the most important and useful thing you can get from JProfiler.
- Note: The JProfiler client only includes platform-dependent files for the client's operating system. Therefore, it might be necessary to download the client for the server platform for your InfoSphere MDM Collaboration Server in addition to the client platform server.
JProfiler is just that: simple and powerful at the same time. Configuring sessions is straight-forward, third party integrations make getting started a breeze and profiling data is presented in a natural way. On all levels, JProfiler has been carefully designed to help you get started with solving your problems. Learn about JProfiler.

Understanding JProfiler
First JProfiler is a tool to understand what is going on inside a running JVM. Before we run the test, we should understand the basic functionality of JProfiler and how it will help us in performance improvement.
There are three aspects to JProfiler:
Time Profiling – This measures the execution paths of your application on the method level.
Memory Profiling – This provides the in-depth understand of heap usage by the application. Askey sound cards & media devices driver download for windows.
Thread Profiling – This analyses the thread synchronization issues.
Jprofiler Vs Yourkit
JProfiler combines time, memory and thread profilers in a single application.
Performance Test
Uncode wordpress theme. In this test, we will be profiling java code of the application. You can download JProfiler as a standalone tool to run or download a plugin with IntelliJ which is what I have done in my case.
Once you start IntelliJ for your web application either locally or remotely, you will see an icon on top right to start the JProfiler. If you are running the application locally, JProfiler will launch and will ask user to find the directory where JProfiler.exe is located, once you click OK, it will start the application server (from intelliJ RUN configuration).
In Filter Settings , you can select the option Edit and it will launch another window where you can provide other application related settings. You can also run JProfiler for a remote application. For that you can provide the application’s host and port address in this application settings.
Application Settings
In my case, I am running the application locally, so I will skip these settings for right now.
Once the OK button is clicked, it will launch the tomcat webserver that I am using in this Spring based web application. I will launch my application in another browser window and do the necessary testing with application. JProfiler should profile my activity. Once you do that, we can verify CPU view for hot spots that Profiler found in our application. This will look like below:
One good thing about this feature is that it shows where the application is taking more time and it is arranged in descending order. So most of the time that my code is taking in the libraries that I am using. If you expand each node, you will find in detail about each method that is getting called.

Jprofiler How To Use
In this post, I showed how to use JProfiler. This was an introductory post as I have not talked about different views that JProfiler offers for profiling the application.
