STS still so slow after doing all these steps
<p>I am using Spring 3.7.3.RELEASE on MacBook Pro Retina with 128GB SSD. While doing any kind of operations like saving the changes, refreshing the project, building the project, while debugging, while synching with VCS etc, it becomes so slow. I have already did the following things,</p>

<blockquote>
  <ol>
  <li><p>Unchecked all plugins in Windows -> Preferences -> General -> Startup and Shutdown except spring maven integration tool</p></li>
  <li><p>Disabled automatic builds under Install/updated and Label Decorator</p></li>
  <li><p>Upgraded to the latest JVM </p></li>
  <li><p>Disabled all validations</p></li>
  </ol>

<pre><code>Model Name: MacBook Pro
Model Identifier:   MacBookPro12,1
Processor Name: Intel Core i5
Processor Speed:    2.7 GHz
Number of Processors:   1

<p><strong>STS configuration:</strong></p>

<pre><code>-clean
