In fact, I'm reasonably sure its meant to be more like a "swap backed FS" which just -happens- to be cached in RAM. I used to configure very minimal swap on machines w/ large amounts of RAM - why bother with lots of swap? If the app server has to start paging then performance will bottom out very quickly! - however then tmpfs'es started showing up in Linux and these want more swap space so long-held temporary files don't hold up precious RAM. 2c, Adrian -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
