title: Diference between jdk/bin/java and jdk/jre/bin/java
body: <p>Making somes tests this week i found this situation:</p>
  
  <p>When i run the tomcat using the java executable in jdk/jre/bin/java the performance is a lot betther than when i run with jdk/bin/java.
  The question is: Someone knows why the jdk package delivers 2 java executables and what is the difference between them that justifies the performance difference?</p>
