title: Eclipse 3.5 (and newer) switching tab is very slow
body: <p>I am using eclipse 3.5 (cocoa build) on Macos 10.5 with Java 1.5.0.19.</p>
  
  <p>I just have 3 java files opened 
  1 files ~ 2000 lines
  the other 2 are ~ 700 lines.</p>
  
  <p>But when I switch from 1 file tab to another, eclipse takes a long time (~ 20 seconds) to switch to another tab.</p>
  
  <p>I have already change the eclipse.ini to</p>
  
  <pre><code>more eclipse.ini
  -startup
  ../../../plugins/org.eclipse.equinox.launcher_1.0.200.v20090520.jar
  --launcher.library
  ../../../plugins/org.eclipse.equinox.launcher.cocoa.macosx_1.0.0.v20090519
  -product
  org.eclipse.epp.package.jee.product
  -showsplash
  org.eclipse.platform
  --launcher.XXMaxPermSize
  256m
  -vmargs
  -Dosgi.requiredJavaVersion=1.5
  -XstartOnFirstThread

  -Xms128m
  -Xmx1024m
  -Xdock:icon=../Resources/Eclipse.icns
  -XstartOnFirstThread
  -Dorg.eclipse.swt.internal.carbon.smallFonts
  </code></pre>
  
  <p>Is there any way to make eclipse 3.5 more speedy?</p>
  
  <p>Thank you.</p>
