Do you have a performance problem? > I am seeing the Survivor Space is highly consumed almost > all times. That is not at all unusual; why do think it's a problem? > I have reduced the survivor ratio to 6. Why? That more than likely just upsets the balance between eden and survivor spaces. > But unfortunately no improvements. You haven't indicated that there's a problem, so what are you really trying to fix? > I have changed the MaxPermSize as 256 from 64 Which has nothing to do with the survivor space. Don't change things randomly. > Can you please suggest me a correct option to increase the > survivor space?
