Performance Testing Statistics

I did a Google search on "performance testing statistics" and was disappointed by what I found. It seems that most of the results are about tools gathering data during the test. I was hoping to find out more about how the industry of load and performance testing compiles information on a macro level.

Here is the best source I found on performance testing statistics that relate to how companies use application performance management. Especially useful are the statistics around how performance affect customers and impact revenue.

The #1 result in Google is a blog post entitled Performance Testing Kills GM. It's a clever conclusion, but I don't see why it gets that high of a ranking. Silly actually.
