title: Java runs really slow on CentOS minimal install, but fast on normal install
body: <p>Using CentOS 6.2, both of these installations are on the same server: </p>
  
  <p>After doing a 'minimal' install Java programs run incredibly slow. 
  After doing a 'software development workstation' install Java programs run at normal speed.</p>
  
  <p>Some information gathered so far: </p>
  
  <ul>
  <li><p>Enabling services not present in the minimal install, e.g., <code>irqbalance</code>, <code>cpuspeed</code> has not helped</p></li>
  <li><p>Have done benchmarks using <a href="http://www.phoronix-test-suite.com/" rel="nofollow">Phoronix</a> suite to test CPU/RAM/HD speed. These tests all run fine on both installs.</p></li>
  <li><p>Have done benchmarks using <a href="http://dacapobench.org/" rel="nofollow">DaCapo</a> suite (which is in Java). These tests all run <em>terribly</em> (that is, 5-50 times slower) on the minimal install.</p></li>
  <li><p>Have tried multiple versions of JRE: OpenJDK 6, Sun Java 6, Sun Java 7</p></li>
  <li><p>Have updated to the latest packages with yum</p></li>
  <li><p>Have verified this slowdown multiple times on two different servers.</p></li>
  <li><p>Both servers use Xeon dual core processors, and have 16GB of RAM or more</p></li>
  </ul>
  
  <p>Anyone have any idea what could cause this?</p>
