If you see the chart for CPU and bandwidth, you will notice that no network requests were made. However, the CPU is flat at 100%. This would indicate that it is doing the heavy lifting of parsing stylesheets, JS files and building the DOM tree or decoding and rendering images.

I re-ran WPT with the timing and trace enabled. I am still learning this part of chrome tools. I can see a lot of activity that appears to be image rendering. Maybe someone on the forum can help you decode the output:

What are the best practices to optimize this?
