Introducing bytecode caching for Vercel Functions

Vercel announced an experimental bytecode caching feature for Vercel Functions that reduces cold start latency by up to 27% for large applications.

• The feature caches compiled bytecode from the first execution and reuses it on subsequent cold starts, eliminating the compilation step.
• It is available for Node.js 20 and frameworks that compile to CommonJS, with an opt-in environment variable.
