This repository is based on https://github.com/webpack/benchmark

Usage

./scripts/bench-all.sh ${platform}

example

./scripts/bench-all.sh linux

If you only want run specific benchmark in some case, make sure you export BENCHMARK_PLATFORM variable

example

export BENCHMARK_PLATFORM=mac

Case

all

A combination of atlaskit-editor, common-libs, common-libs-chunks, rome

atlaskit-editor

Basic react application with @atlaskit/editor-core

common-libs

A combination of some widely used libraries in Javascript ecosystem.

common-libs-chunks

Same as common-libs, but using async import() syntax to force bundler generate multiple chunks.

rc-1000

1000 react components (each component have 200 line of code) to simulate real application in development mode and production mode.

rc-10000-hmr

10000 react components (each component only have basic skeleton, complicated application rerender time may greater than hmr time) to test hot module replacement performance of each devServer of bundler.

rome

Configuration

Using swc loader and swc minifier that could maximize performance of each bundler which is same as in rspack internally.

webpack

module.exports = {
	optimization: {
+		minimizer: [
+			new TerserPlugin({
+				minify: TerserPlugin.swcMinify,
+				// `terserOptions` options will be passed to `swc` (`@swc/core`)
+				// Link to options - https://swc.rs/docs/config-js-minify
+				terserOptions: {},
+			}),
+		],
	},
	module: {
		rules: [
			{
				test: /\.ts$/,
				exclude: /(node_modules|bower_components)/,
				use: {
-				loader: "ts-loader",
+				loader: "swc-loader",
+					options: {
+						jsc: {
+							parser: {
+								syntax: "typescript",
+							},
+						},
+					},
				},
			},
		],
	},
};

parcel

+{
+	"extends": "@parcel/config-default",
+	"optimizers": { "*.js": ["@parcel/optimizer-swc"] }
+}

We have't replace the transformer because parcel has used swc internally to speed up them transformation
