These days I try to do some stress testing and performance optimization for the project, and also make a summary of the used test tools, and make a summary of the relevant data for later use. 1 Introduction Improving application performance is a time-consuming effort, but it is often not obvious what functions in a program consume most of the execution time. Th

ObjectiveIn the ordinary course of work, sometimes encounter outofmemoryerror, we know that encountered error generally indicates that the program has a serious problem, may be catastrophic. So it is very important to find out what causes outofmemoryerror. Now we introduce the Eclipse Memory Analyzer tool (MAT) to resolve the challenges we face. If not stated, this article uses the Java 5.0 on Windows XP SP3 environment.Why use Mat?Previously, I think it's right to use
