Eclipse: Memory/JVM Optimizations (.eclipse.ini)

Found a helpful post for setting your Eclipse IDE environment. Eclipse is a big memory hog so you can increase Eclipse’s memory setting in the [eclipse path]/.eclipse.ini file.

Here is what I change/add:

-XX:PermSize=256m
-XX:MaxPermSize=512m
-Xms1024m
-Xmx1024m

According to blog.normation.com PermSize controls the size allocated to compiled classes and permanent data structure.

-Xms and -Xmx are JVM setting and they stand for: src
-Xms initial java heap size
-Xmx maximum java heap size
In scouring articles, most people set these values to the same value.
