Eclipse 3.5.1 uses a lot of memory

Question

I switched to Eclipse 3.5.1 and noticed that it takes 560 mb when doing a clean build. And the memory is not collected after use. This is true.

Any solution for this?

JVM: jdk1.6.0_17 Windows XP, 2GM RAM

Below is my eclipse.ini

-showlocation
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
384m
-startup
plugins/org.eclipse.equinox.launcher_1.0.201.R35x_v20090715.jar

I spent a lot of time on memory issues related to Eclipse, especially with Eclipse 3.2 and the shameful PermGen problem.

A few things that can make a difference:

1) Remove the memory used for the initial heap size: -Xms40m instead of -Xms128m. 2) Do not set the minimum size PermGen: remove -XX: PermSize = 128m

According to my experiments, all the vmargs options installed in ini are played only once - when creating a new workspace. If you want to change the settings in an existing workspace, use the run / debug configuration. vmargs in ini will no longer be read.
