![]() The “Patty” project is an open-source project available to download from Source Forge and is aimed at providing a profiling tool for Java 1.5.0 and higher Virtual Machines. Java Performance Analysis Tool (Patty) *Beta Visual VM can do CPU Profiling, Memory Profiling, run garbage collections, take snapshots and more. It is possible to also save and capture the data about the JVM software and save the data to the local system, and then view the data later or share it with others. ![]() Data generated can be generated and retrieved by the Java Development Kit (JDK) tools and all the data and information on multiple Java Applications can be viewed quickly both local and remote running applications. Visual VM allows you to get detailed information about your Java applications while they are running on a Java Virtual Machine (JVM). VisualVM is a tool derived from the NetBeans platform and its architecture is modular in design meaning it’s easy to extend through the use of plugins. GC Viewer is an open-sourced tool by tagtrum industries incorporated is a tiny Raleigh, North Carolina based software and consulting company founded in 2004 from the not-for-profit project tagtraum industries started in 1999. It is often very useful when you want to tune the garbage collection of a particular application by changing generation sizes or setting up the initial heap size. GC Viewer can be used to calculate garbage collection-related performance metrics which include throughput, accumulated pauses, longest pause and more. GC Viewer is available to be downloaded for free (from its website and GitHub)and is an open-sourced tool that can be used to visualize data produced by the Java VM options using the vmflags -verbose:gc and -Xloggc. JProfiler is a commercially licensed Java profiling tool developed by EJ-technologies GmbH and is mainly designed for use with Java EE and Java SE applications. JProfilerwas previously mentioned in my previous article but remains an extremely good Java profiler combining CPU, Memory and Thread profiling into one application and is useful for developers as it can be used to analyze performance bottlenecks, memory leaks, CPU loads and resolve threading issues and supports local profiling (analysis of applications that are running on the same machine on which the JProfiler software is installed) and remote profiling (this is where it allows for the analysis of Java applications which are running on remote machines which JProfiler software is not installed on.). This profiler includes functions such as CPU, memory and threads profiling but also provides additional tools and functionality for basic JVM monitoring, which is extremely useful for developers who need to solve memory or performance-related issues. NetBeans IDE supports the development of all Java application types (Java SE (including JavaFX), Java ME, web, EJB and mobile applications) out of the box. The NetBeans profiler is a modular add-on that is used to provide the profiling functionality for the NetBeans IDE, which is an open-source integrated development environment. NetBeans Profiler NetBeans Profiler is found in NetBeans In this article I will be taking a look at 9 tools to help you with Java Performance Tuning, some are used by us at IDR Solutions and others that we may use for personal projects. I have noticed that recently one of the areas of focus has been on improving and Java Performance. At IDR Solutions we are always looking at ways to improve our code and lately, we have been looking at improving our java code in Buildvu (our PDF to HTML5 Converter), JDeli (our Java Image Library) and JPedal (our Java PDF Library). Previously I wrote an article about 5 tools to help you write better java code which helped to improve our code but also our productivity.
