Reality
A 1,036-file React Router build ran its compile step in 0.81 seconds on oxc's native React Compiler, down from 14.3 under Babel, and the whole build still takes 9.3. Opting in needs one config key and Vite v8.

Roughly 2 GB per JavaScript build, a hard failure floor at 2 GB of RAM, and a formula that subtracts headroom first. Exceed it and the 504s land on sites nobody was deploying.
Reality
Vite fixes the build times and the config cliff that retired Create React App, and keeps the client-only rendering. Next.js fixes that, and charges for it.

A six-route commerce app rebuilt in Kudzu, Astro, React Router, TanStack Start and Next.js argues hydration cost is the number to defend. The harness is open source, so the claim is attackable.
Reality
The one-line Express 5 replacement claims 2x to 20x faster routing. Its author is explicit that the spread lands on thousand-route tables, not on hello world.
