Most of the applications today are designed and developed for simultaneous use by a large number of users. At times there are underlying problems in the code, which may cause error conditions such as Memory leaks, Race conditions, Thread locks and so on which if neglected, stretches the use of resources beyond limits, causing the application to slow down or even crash. Thus, it becomes critical for the developer to ensure that the application is available, reliable, scalable and makes the most optimal use of the available resources. Faster, efficient and more powerful machines temporarily hide performance and other problems, but errors in code if left unidentified can cause major application as well as system performance issues. To detect such coding faults manually is an extremely tedious, error prone and expensive task. AppPerfect Java Profiler is designed to assist you find such errors by profiling your application as well as vital resources of the system on which you are running the application. Profiling is the process of monitoring various JVM level parameters such as Method Execution, Thread Execution, Object Creation and Garbage Collection. It will provide you with a finer view of your target application execution and its resource utilization. AppPerfect Java Profiler eliminates the need to spend long hours going through the code, and pinpoints the problems associated with your application. It provides complete and accurate statistical information that helps you trace coding errors in your application. AppPerfect Java Profiler helps you diagnose and resolve performance problems, memory leaks and multi-threading problems in your Java or J2EE server applications to ensure the highest level of stability and scalability for your applications. AppPerfect Java Profiler provides you with a root-cause analysis of these problems and helps you resolve them.
