it used to be solaris (i don't know if this is still the case) would evict pages to swap even when used + cache << phys memory. i did quite a bit of performance work on solaris, and found i couldn't use more than a fraction of available memory. we moved the same applications to aix and got much better performance with the same amount of physical memory, as we were memory bound. - erik
