What does the waterfall tool do?
- Another vital point is that the waterfall chart lets you see the order in which assets are rendered in your browser. The order can be very vital as this can affect all sorts of things, from render-blocking CSS to FOIT issues.
- The Waterfall graph can simply be used as a timeline to track requests. It provides a visual representation of the duration of the requests spent in the queue, the duration to get the response, and to download the resources.
- Additionally, when you hover over any of the queues inside the graph, it displays in-depth information about it.
- A useful feature of the Waterfall graph is the ability to narrow down the scope of requests that are displayed to a certain point in the timeline.
