# Add automated benchmark runner for module-cost

## What?
This PR adds an automated benchmark runner for the module-cost benchmark, allowing for consistent measurement of module loading and execution times.

## Why?

It is to tedious and error prone to run the benchmark. 

## Usage

Build `next` and turbopack however you like
```
pnpm i
pnpm prepare-bench
pnpm build-webpack (or build-turbopack)
pnpm benchmark
```

## How?
