All,

If tempdb recomendation is 1 datafile per cpu and we know that 1 cpu usually support 1 worker thread.

Will a particaular spid utilize more than 1 tempdb datafile if it exceeds the size of the current file it is assigned??

thanks

SQL Server uses a proportional fill algorithm for multiple data files, it does not have anything to do with a particular spid. Spids do not get assigned to a file.
