Steve, I wonder if you don't have too many tempdb files. I have lost track of the number of clients I have come across that cause IO performance problems by having too many files (of any SQL Server type) on too few spindles. Causes head thrashing and you get killed by the disk access/seek times. Unless you have demonstrated tempdb object allocation issues or have a boatload of spindles (or SSDs) you may get better IO with fewer files.

Best,

Good point. Our IT staff used the best advice at the time, which was 1 per core. It's possible that we should reduce down to 4 files.

Once again great article and great tool.

I am still trying to work out how to get Blitz to count the number of instances on one server. :ermm:

Cheers
