title: Why is SpringSource Tool Suite (STS) so slow? And how can I fix it?
body: <p>I've been running STS 2.3.2 on a MacBook Pro for a few days now. I'm finding the performance to be significantly slower than any other build of Eclipse I've used. For example, switching from one tab to another can take up to 4 seconds.</p>
  
  <p>I tried turning off much of the validation, and increasing the memory, but it's not making a difference.</p>
  
  <p>Are others having similar experiences?</p>
