Vercel 官方分享了升級 Next.js 所帶來的即時效能提升。透過引入基於 Rust 的 SWC 編譯器取代 Babel，專案的建置速度與快速重新整理皆獲得數倍增長。此外，新版本在圖片優化、中介軟體（Middleware）及伺服器端渲染（SSR）上也進行了大幅優化，讓開發者與終端用戶都能獲得極致體驗，是提升 Lighthouse 分數的捷徑。
This official blog post from Vercel explores how simply upgrading the Next.js version can deliver immediate, tangible performance improvements to web projects. In front-end development, as a project grows in scale, build time and Hot Module Replacement (Fast Refresh) during development tend to slow down, directly impacting developer productivity. Next.js has addressed this by introducing a brand-new Rust-based compiler, SWC, as a replacement for the traditional Babel toolchain. This change delivers up to a 5x improvement in compilation speed and a 3x improvement in Fast Refresh speed.
