    Question about "MaxHeapFreeRatio" parameter

      According to http://java.sun.com/javase/technologies/hotspot/vmoptions.jsp , default value is -XX:MaxHeapFreeRatio=70 , is that really good to have 70% of heap as free? I change it to -XX:MaxHeapFreeRatio=40 and running eclipse, I find it consume a lot less memory without notice performance issue.
