How do I increase the heap size for Eclipse?

Posted Mon, 2010-08-16 14:26

We recommend to increase the default heap size settings of Eclipse. You can do this by adding following lines to eclipse.ini in your Eclipse installation folder:

-vmargs
-Xmx1400m

This sets the maximum heap size to 1400 MB. If you system has plenty of memory, you can even choose higher numbers.

Note: If your eclipse.ini already contains these arguments, you should not append these parameters again, but instead modify the existing values. If -vmargs is there already, but -Xmx1400m is not; you should add -Xmx1400m after the existing -vmargs.
