Run Time Stats
Runtime apps implement comparable benchmark routes across frameworks. See Default Benchmark Setup for the shared environment and each framework’s build tool and adapter. Test-specific differences are documented in the linked methodology sections below.
Client Side Rendered Tests
Section titled “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.

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.
