title: Why is Eclipse so slow at saving individual JavaScript, HTML and CSS files only?
body: <p>I am using Spring's bundle of Eclipse, STS version 3.6.0 which is based on Eclipse Kepler SR2 (4.3.2).  Eclipse performance is generally very good and if I save a <code>Java</code> file, it is instantaneous. However, when I try to save a <code>JavaScript</code> file it can take up to 3 seconds to save and the entire IDE is frozen during the process, which is very annoying and it actually impacts productivity.  I have done some digging and apparently, there are validators and such that cause slow down so I have tried turning these off but it doesn't make a difference.</p>
  
  <p>The problem also occurs with CSS and HTML file types so I'm sure it's specifically with the web-development plugins.  Can anyone suggest a way of fixing this?  I am willing to disable features to improve the save times if necessary. </p>
  
  <p><em>Note: I am using stock version of STS - no extra plugins.</em></p>
