title: jprofiler overhead between two test runs in java
body: <p>I have two classes</p>
  
  <p>Queue Writer = this class marshal the object and store xml in Message Queue(RabbitMQ)<br>
  DB Writer = this class read xml from queue and un-marshal the xml and save into database.</p>
  
  <p>Now I have doing comparison either should use xml( using jaxb) or use json( using jackson) for better performance.</p>
  
  <p>I made a test of 100,000 records ,and both have taken the same time.</p>
  
  <p>Then I download jprofiler and  made two test. But actually , I have used this tool first time and I am not able to find the difference, accurately.</p>
  
  <p>can you please tell me , on what area i can find the overhead between two test.</p>
