RE: Help interpreting waterfall diagram
The dark parts are when it is actually downloading content for the request and the light parts are when the request data is idle. There are a lot of different causes for gaps:

- HTML early flushing where headers and some initial data is sent right away but the rest of the HTML is delayed until some back-end operations complete.
- TCP slow start
- Contention with other requests (or connections)
