Hi, I am reading sun performance paper: Performance Oriented System Administration and see the following setense: "However, sizing swap to be too large can cause hard-pageout to occur too easily" I do not understand what on earth this mean, can some one kindly explain this? And why it will make hard-pageout occur?Is there documents talking about this feature? Thanks.
