title: Rubymine 5.4.3.2.1 freezes sometimes
body: <p>I am using Rubymine to work on a suite of rails projects. There are quite a bit of gems and source files, but I think rubymine should be able to handle everything despite the size...</p>
  
  <p>My sources files (and gems) are shared in a Vagrant box (see <a href="https://stackoverflow.com/a/19662310/311744">https://stackoverflow.com/a/19662310/311744</a>).</p>
  
  <p>Sometimes, when I am editing, Rubymine freezes. (about 5-6 seconds).</p>
  
  <p>Usually, 3-4 minutes after I restart the IDE, everything is fine. Then I have one big 5 seconds freeze, and then from that point every 15-20 seconds I have a new freeze. During a freeze, Rubymine takes 100% (or a big part) of the CPU. </p>
  
  <p>I am running on MacOS 10.8.5 on a recent MBPr.</p>
  
  <p>I don't want to give up Rubymine. How can I troubleshoot that ?</p>
