Eclipse 3.5 (and newer) switching tab is very slow

Question

I am using eclipse 3.5 (cocoa build) on Macos 10.5 with Java 1.5.0.19.

I just have 3 java files opened 1 files ~ 2000 lines the other 2 are ~ 700 lines.

But when I switch from 1 file tab to another, eclipse takes a long time (~ 20 seconds) to switch to another tab.

I have already change the eclipse.ini to

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 -Dorg.eclipse.swt.internal.carbon.smallFonts -XX:MaxPermSize=512m -Xms128m -Xmx1024m -Xdock:icon=../Resources/Eclipse.icns -XstartOnFirstThread -Dorg.eclipse.swt.internal.carbon.smallFonts 

Is there any way to make eclipse 3.5 more speedy?

Thank you.

Answer 1

I switched this line in the eclipse.ini file (found inside the eclipse application package):

-Dosgi.requiredJavaVersion=1.5 

to

-Dosgi.requiredJavaVersion=1.6 

and tab switching was speedy again.
