Have you ever asked yourself these questions?

"I made my pages faster, but my business and user engagement metrics didn't change. WHY???"
"How do I know how fast my site should be?"
"How can I demonstrate the business value of page speed to people in my organization?"

The answers might lie with identifying and understanding the performance plateau for your site.
