Analyzing Storage Performance using the Windows Performance Analysis Toolkit (WPT)

I wanted to make sure everyone has seen this excellent blog posting from Robert Smith in Premier Field Engineering (PFE), on using the WPT to get to the bottom of performance issues with the Storage Stack. Please check out his post and use this the next time you have a performance issue with Storage.


This includes the following topics:


  • Obtaining the WPT
  • Getting Started: Capturing Storage Performance Data
    • Considerations for starting a trace
    • Stopping a trace
  • Trace Analysis
  • What to look for (in a trace)
  • High Disk service times
  • Storport Tracing
  • High I/O Times
