Webpack vs Rspack Benchmarks (Huly Monorepo)

This file tracks the performance metrics for the transition from Webpack to Rspack.

1. Full Builds & Initial Startup

Metric	Webpack (Original)	Rspack (New)	Improvement
Production Build (package vs rs:build)	2m 50s (170s)	47s	~3.6x
Dev Server Cold Start	1m 00s (60s)	43s	~1.4x

Note

Cold start improvement is lower because Rspack is now correctly bundling all dynamic resources upfront to prevent the "refresh waterfall."

2. Hot Module Replacement (HMR)

Metric	Webpack	Rspack	Improvement
Single Component Recompile	16.2s	0.8s	~20x
