Hey Spiceheads,
I have been researching adding additional TempDB files to our SQL 2008 installation, and I ran across an article at Brent Ozars' site that recommended setting the TempDB files to a fixed size, to prevent them from growing to different sizes and causing havok with the file selection mechanism.
What do you folks think ?
