J-Sprint 2.0: Performance Analyzer
Performance is a crucial aspect in developing any application,a simple memory leak or other performance flaw can create all kinds of hassles including shutting down mission-critical applications, flooding the tech support lines, not to mention causing software engineers to lose sleep and start drinking again. Unfortunately, analyzing applications can be a daunting task, especially on a budget. J-Sprint wants to help you out by offering a fairly easy-to-use performance analyzer. Using J-Sprint, you can analyze stand-alone Java applications, applets and even servlets(being run on Tomcat 4/5 or JBoss). To test an application, you simply provide the location of your JVM, select the type of Java application you wish to test and enter any other parameters required to run your application. When complete, J-Sprint will output a full report, either of CPU statistics or of memory statistics(chosen prior to testing). These HTML pages can be printed or exported in the registered version.
Your next task will be to analyze the output and determine what that means for your application. What J-Sprint will not do is tell you what lines to correct or how to correct them. It either(in the case of CPU analysis) takes statistical samples by retrieving a stack trace of all the threads running in your application or(in the case of memory analysis) records the type and size of each object, the method and line being executed and the allocation context(the documentation will explain what this is). From this information, J-Sprint can determine and report information about how your application performs.
Installing J-Sprint was fairly simple, download the .exe. Make sure to put it where you want it to stay. On the first execution, it will create the necessary configuration file and other resources it needs to execute. J-Sprint requires Windows
98/NT(3.51 or higher)/2000/XP. Additionally, you will need to have MS Internet Explorer 4.0 or higher, 64 MB RAM (128 MB recommended) and a JVM that supports the Java Virtual Machine Profiling Interface (the new JDKs from Sun will support this). Registration is currently only $50.
