To speed up Next.js dev server startup and HMR, enable Turbopack for incremental bundling and file-system caching. This reduces iteration time by processing only changed modules, accelerating local development for large Next.js 16+ projects.

Use Turbopack for faster local development with incremental bundling, and use Webpack when specific plugins or edge cases require it. Turbopack targets dev server performance, while Webpack may be necessary for certain production build configurations.

Slow Next.js 16+ development performance often stems from lacking incremental bundling and file-system caching. Turbopack addresses this by caching file changes and accelerating hot module replacement, reducing iteration time for large projects.

Turbopack may not support all existing Webpack plugins. When specific plugins or edge cases are required, Webpack may be preferred over Turbopack to ensure compatibility during your Next.js development and build processes.

Turbopack provides incremental bundling and file-system caching to speed up Next.js development servers. By tracking file changes, it minimizes rebuilds and accelerates hot module replacement, significantly improving dev iteration time.
