Client Side Rendered Tests

Methodology: Client Side Rendered Tests.

Some frameworks have been moved off their golden path to make client side tests fair when comparing. See the methodology link above for the full details.

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
• Presentation delay
