title: Java split String performances
body: <p>Here is the current code in my application:</p>
  <pre><code>String[] ids = str.split(&quot;/&quot;);
  </code></pre>
  <p>When profiling the application, a non-negligeable time is spent string splitting. Also, the <code>split</code> method takes a regular expression, which is superfluous here.</p>
  <p>What alternative can I use in order to optimize the string splitting? Is <code>StringUtils.split</code> faster?</p>
  <p>(I would've tried and tested myself but profiling my application takes a lot of time.)</p>
