Much faster but incompatible with some standard library middlewares. ### Prefork Spawn multiple processes (SO_REUSEPORT) to utilize all cores. ## Best Practices (2025) **Do**: - **Use `v3`**: For stable generic support. - **Be careful with Prefork**: Can cause issues with socket connections if not handled. - **Use Built-in Middleware**: Cache, Compress, CORS are highly optimized. **Don't**: - **Don't hold references**: `fasthttp` reuses context objects. Copy strings if you need them after handler returns. ## References - [Fiber Documentation](https://gofiber.io/) --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/g1joshi) — claim your Tome and manage your conversions.
