Thanks for teh question. It made me look in BoL, which some say is cheating (and I say is learning).

I had to do the same (look i BOL), but I don't consider that cheating. "Cheating" in my opinion is when you copy/paste/run the T-SQL and post the answer without utilizing a single neuron in the central nervous system.

The bad news is that, according to BOL, "this view is applicable only to the tempdb database".
I would not expect much change in SGAM pages in a normal database. Table creation rates should be low compared to tempdb, so frequent changes in SGAM page allocation is unusual.


I believe this is more important to monitor when you are using Mirroing or Publishing a VLDB.
Also it may be usefull you execute large querries (5K+ rows) that use TEMP tables or Table Parameters that have to create objects to store data in TEMPdB.

No, Nils is quite correct.

I have no idea why you think mirroring, or publishing a large database would be a prime factor in tempdb SGAM contention.
Where does your magic figure of 5K+ rows come from, or are you just guessing?
