I apoligize in advance if this question is indeed too subjective as SO warns me.

My workstation has 8 gb of ram and runs windows 7 64 bit. I use the Spring tool Suite (3.1) but as soon as i am starting to open and modify the spring config (.xml) files, STS becomes incredibly slow.

I already tried switching off "build automatically" and to increase memory settings but no luck.

How should i change my .ini ? this is what i have set now:

-vm
C:/Program Files/Java/jdk1.7.0_07/bin/javaw.exe
-startup
plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.200.v20120522-1813
-product
org.springsource.sts.ide
--launcher.defaultAction
openFile
--launcher.XXMaxPermSize
4096M
-vmargs
-Dosgi.requiredJavaVersion=1.5
-Xms512m
-Xmx2048m
-XX:MaxPermSize=512m

My collageu running the same project in IntelliJ, has no problems.

Thank you!
