Eclipse Juno + WTP +EGit dead slow

Question

I'm trying to use Eclipse Juno (Version: 4.2.0 Build id: I20120608-1400) with WTP for JavaScript/Node.js development on MacOSX Lion, on my 4GB RAM MacBook Pro. Sometimes it gets dead slow, and unusable. I've tried tweaking both through preferences (disabled all validators) and initialization variables, and also upgraded to 1.7 VM as recommended. Here's the contents of my eclipse.ini file:

-startup
../../../plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar
--launcher.library
../../../plugins/org.eclipse.equinox.launcher.cocoa.macosx.x86_64_1.1.200.v20120522-1813
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m
--launcher.defaultAction
openFile
-vm
/Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home/bin/java
-vmargs
-Xms64m
-Xmx256m
-Xdock:icon=../Resources/Eclipse.icns
-XstartOnFirstThread
-Dorg.eclipse.swt.internal.carbon.smallFonts
-XX:+UseParallelGC
-XX:+UseCompressedOops
-XX:MaxPermSize=256m
-server

Can someone advise what I could do to improve WTP performance?

Answer 1

unfortunately i can second that. juno is unusable slow in comparison to indigo. with every click i have to wait multiple seconds for a reaction of the gui. i too can exclude the reason might be on the side of my hardware.
