Benchmarks

To track our progress and validate our assumptions, we run benchmarks regularly on the Turbopack repo against Vite and previous versions of Next.js.

Metrics

Let's break down exactly what each of these metrics mean, and how they'll impact your day-to-day developer experience.

Cold startup time

This test measures how fast a dev server starts up on an application of various sizes.

To measure this, we run an end-to-end test which:

1. Generates an application with a set number of JS modules
2. Runs the dev server on localhost:3000
3. Visits localhost:3000 in Chrome
4. Waits until the site has finished loading its last module.

File updates

We also measure how quickly your dev server updates when a source file changes. This helps us get a sense for how fast your dev server will respond to updates.

This uses a similar setup:

1. Generates an application with a set number of JS modules
2. Runs the dev server on localhost:3000
3. Visits localhost:3000 in Chrome
4. Changes a module in the file system.
5. Waits until the site has finished loading the new module.
