gabrielduartem / bundler-performance-benchmark

This is a super tiny example of a transparent comparison between parcel and webpack and anyone else who wants to be involved.

bundler-performance-benchmark

Why

Showing numbers means nothing if you can't back it up. This is a joint effort between all bundlers involved to create a fair and unbiased set of benchmarks for build and size performance.

How to Run

• Clone repo
• run yarn
• run yarn build:webpack && yarn build:parcel
• Run again for cache times

Single Entry, Production, Medium Graph, JS Only

bundler	version	build time	build time w/ cache	bundle size	config LOC
webpack	webpack/webpack#next	340ms	184ms	5.72kb	15
parcel-bundler	1.2.1	1.78s	473ms	21.094kb	0

Parcel Recipes (Preact)

bundler	version	build time	build time w/ cache	bundle size	config LOC
webpack	webpack/webpack#next	1172ms	700ms	9.69k	20
parcel-bundler	1.2.1	1270ms	266ms	11.560kb	5

Help Wanted

Need help organizing and setting up multiple real world scenarios for all bundlers to run.

Feel free to checkout existing example or optimize the workflow via PR.
