FreeLists / oracle-l / OT: question about sizing swap for solaris

["zhu chao" <chao_ping@xxxxxxxxxxx>]

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.
Zhu Chao.
