How can I find the size of the files in tempdb when SQL Server was last started? I know that each time I stop and start SQL Server, it drops, then recreates tempdb. So, SQL Server resets the size of the tempdb files to their original size as of the last SQL Server restart or to the size the files were last manually set to through an ALTER command. I know that performance can decrease if my tempdb files need to grow substantially during normal processing. I'd like to see how much tempdb files have grown so that I can determine whether to manually set them to a larger size.
