Interaction Breakdown

Total latency is split into the three consecutive phases reported by Lighthouse.

• The input delay, which starts when the user initiates an interaction with the page, and ends when the event callbacks for the interaction begin to run.
• The processing duration, which consists of the time it takes for event callbacks to run to completion.
• The presentation delay, which is the time it takes for the browser to present the next frame which contains the visual result of the interaction.

• Input delay
• Processing duration

SSR Load Test

Methodology: SSR Load Test.

All eight frameworks render the same 1,000-row, three-column table using ordinary <a> links. This compares server rendering under HTTP load without the extra work of rendering framework router link components. Requests still pass through each framework’s server routing. No browser runs and no links are clicked.
