Run Time Stats

Setup

Section titled “Setup”

Run Time benchmarks use each meta-framework’s app-* package.

Currently, each test uses a different route in its app, configured to meet each test’s requirements.

See Default Benchmark Setup for the base set-up. Each test’s specific setup is linked in the methodology with links in each section.

Client Side Rendered Tests (Lighthouse)

Section titled “Client Side Rendered Tests (Lighthouse)”

These CSR browser performance tests use Lighthouse to measure paint timings and a controlled navigation interaction.

Methodology: Client Side Rendered Tests (Lighthouse).

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 (Lighthouse)

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.

Initial Load

Section titled “Initial Load”

Compare the resources transferred on a first visit to the same small, styled landing page. Sizes include response headers; lower is better. Inline CSS and JavaScript count toward HTML. Other includes images, media, fonts, and remaining resources. See Methodology for collection details.

Server Side Throughput Tests

Section titled “Server Side Throughput Tests”

Methodology: Server Side Throughput Tests.

Measures how many requests each framework’s server handler can process per second when rendering a 1,000-row table, and how long each response takes. Requests bypass network overhead to focus on server rendering performance.

SSR Load Test

Section titled “SSR Load Test”

Methodology: SSR Load Test.

Measures server throughput and response latency as concurrent connections increase, with each request rendering a 1,000-row table.

This version uses ordinary <a> links to measure server rendering without the extra work of rendering framework router link components.

Compare it with the router link load test to see how framework router link components affect server rendering performance.

Section titled “SSR Router Link Load Test”

Methodology: SSR Router Link Load Test.

Measures server throughput and response latency as concurrent connections increase, with each request rendering a 1,000-row table using framework router link components.

Compare it with the plain link load test to see how these components affect server rendering performance. These tests make HTTP requests only; they do not measure browser navigation or prefetching.

Frameworks without a router link component are excluded.
