Please share what helped shape your point of view on whether or not to enable TF 1118 in your SQL Server 2008 or 2008 R2 instances.

This trace flag helped me when I was working with SQL Server 2000 about 8 years ago. Since I've stopped working with SQL Server 2000, I did not have to use it.

I'll only use it if I have TempDB contention and splitting the files doesn't help. Haven't needed it since SQL 2000.

I found this article in which the author ran a test with 1 TempDB file. No performance gains were made.

Also found this presentation on Trace Flags, contains section on Production Trace Flags, 1118 being one of them. References white paper.
