Switching editor tabs in Eclipse Juno SR1 is very slow

Eclipse Juno

At work I am forced to use Eclipse, together with the Web Tools Platform (WTP). Lately I’ve found that switching editor tabs is very slow, when editing JSP or JavaScript files. It turns out that this is a specific performance issue of Eclipse Juno SR1. There are two ways to solve it:

  1. Install Eclipse Juno SR2.
  2. Install Juno SR1 Patches/Eclipse UI Juno SR1 Optimizations from the repository http://download.eclipse.org/eclipse/updates/4.2.

    This is not really necessary…..Just edit de eclipse.ini and change the version from 1.5 to 1.6 on this line: -Dosgi.requiredJavaVersion=1.6
