Quoting from http://www.daemonnews.org/200001/freebsd_vm.html :

<snip>*
When To Free a Page*

Since the VM system uses all available memory for disk caching, there

Got to say - a very interesting discussion you have all being having, I
am now quite confused about what those vfs.*buf* variables actually do...

Please feed back any clarfications from the FreeBSD experts to this list!
