Performance tests

How to make performance tests on Java? Such as time of execution, a track of using memory, a track of operations per second and may be there are another helpful tests. How to realize this tests without an influence to the real application work (without this test)? I mean that I could be confident that my application would be work with the same performance on average without those tests.

Note: I need to attach a specific tool to my test class. I know that there is many different tools to test a huge amount of VM parameters of an application. I need to write a test class with distinct test parameters which values I can handle as I want. It would be good if API supported graphical GUI for some those parameters.

I am under the assumption that your servers are hosted on the linux env. Jconsole and Visualvm are indeed helpful to monitor your memory and performance. Just as a work around you can also use sar, top and mpstat commands to get your required values. You will have to install the sar package on your linux server by command sudo apt-get install sysstat. You can refer "http://www.thegeekstuff.com/2011/03/sar-examples/?utm_source=feedburner" to learn more on the commnads. You don't need admin access to configure any of these commnds..

I would recommend jProfile for performance test and jConsole for Monitoring memory usage etc...

You can use tools like jconsole, visual vm especially for the memory. These come bundled with the Jdk. As for the speed of your application, typically log messages can help you with that. If the log messages follow a standard you can pretty much write your own script to give you a pretty formatted result. Also, it is a good idea to write test classes to give you a fair idea of the performance for varying loads.
