title: Will Java app slow down by presence of -Xdebug or only when stepping through code?
body: <p>I realize that Java code will <a href="https://stackoverflow.com/questions/2195720/why-does-java-code-slow-down-in-debugger">slow down</a> when run in debugger.</p>
  
  <p>Question is, will the code slow down simply by starting Java with these options:</p>
  
  <pre><code>Xdebug -Xrunjdwp:transport=dt_socket,address=5005,server=y,suspend=n
  </code></pre>
  
  <p>??</p>
  
  <p>Or does the slowdown only happen when you connect to the "debug port" and actually step through code using an IDE?</p>
