Robert Smith (Platforms Field Engineer) has recently posted a new blog that cover one important area of Windows performance that few people understand well. In his blog post he talks about how to use Windows Performance Toolkit (WPT) in general and the XPerf tool in particular. Xperf.exe is the command line tool used to start, stop, and manage traces. He then goes on to outline how to use the toolkit to look into Storage and know where to start looking when you hit a performance issue.
Here's the outline of his post:
Obtaining the WPT Tools
More About the WPT
Getting Started: Capturing Storage Performance Data
Considerations for Starting a Trace
Stopping a Trace
How to perform Trace Analysis
What to Look For
What are We Doing Here?
High Disk Service Times
Storport Tracing (For Storport storage devices)
High IO Times
If you're interested in Performance (and specially Storage Performance) and you never used the WPT or XPerf.exe before, this is a must read.
