Investigate SQL Server tempdb I/O latency

In my post about increasing your SQL Server performance with tempdb, I talked about performance tuning steps related to the tempdb system database. But of course: as proof or even part of such tuning steps, it is crucial to measure the differences between current and previous implementations. That is why I would like to highlight some useful techniques and provide you with functional insights on how to analyze tempdb I/O stalls or bottlenecks. This information is especially useful if you’re a database administrator!
