Is there any DMV query out there that can calculate the ideal amount of memory currently needed for an Instance?
I feel there just must be a possibity using total target memory, total server memory, free pages, page life exptancy, lazy writes and buffer hit cache ratio.
Not for all queries of course. Just that 90% or so of queries don't need page swapping.
Using this in combination with PAL thresholds would be awesome.
