How to speed up reading files of a project in eclipse - java

I have a liferay 6.2 project with thousand files in source folder
I use eclipse IDE to develop and it has a annoyed issue: each time I click a folder in eclipse, it take long time to open the folder to see files and subfolders
I have config the eclipse.ini of eclipse to tuning eclipse performance but it does not have any effect.
Please me the suggestion to speedup eclipse

Limited BigInteger in eclipse

In Eclipse, I get a value for BigInteger.valueOf(2).pow(31093), but not for BigInteger.valueOf(2).pow(31094) (its empty).
I edited my eclipse.ini like this:
-startup
plugins/org.eclipse.equinox.launcher_1.3.0.v20130327-1440.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.200.v20140116-2212
-product
org.eclipse.epp.package.standard_2.0.2.20140224-0000
--launcher.defaultAction
openFile
--launcher.XXMaxPermSize
1024M
-showsplash
org.eclipse.platform
--launcher.defaultAction
openFile
--launcher.appendVmargs
-vmargs
-Dosgi.requiredJavaVersion=1.7
-XX:+UseParallelGC
-Xms512m
-Xmx1024m
-XX:PermSize=1024M
On other computers I succeeded. Is eclipse still the problem or there is something else?

If it interest anyone - The problem is a bug of the Console view in Eclipse.
Printing very big BigIntegers - same problem. The workaround works.

Java crashes with Java was started but returned exit code=1

If your JDK version is 32bit then download Eclipse or STS of 32 bit.
If your JDK version is 64bit then download Eclipse or STS of 64 bit.This worked for me
