# Accelerate connections

Last updated Aug 24, 2026|Copy as Markdown|[View as Markdown](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/use-cases/performance/connections/index.md)|[Agent setup](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/agent-setup/)

Network congestion and suboptimal routing between your origin and visitors add latency. Cloudflare Argo Smart Routing uses real-time network telemetry to route requests through the fastest paths, while Early Hints preloads assets before the full HTML response arrives.

## Solutions

### Argo Smart Routing

Route traffic through the fastest paths across Cloudflare's network. [Learn more about Argo Smart Routing](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/argo-smart-routing/).

* **Smart routing** \- Automatically route requests through uncongested network paths, reducing latency between edge and origin
* **Optimized paths** \- Real-time network telemetry selects the fastest available route for each request

### Speed

Improve the performance of your website or web application. [Learn more about Speed](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/speed/).

* **Faster handshakes** \- Assess the performance of your website and gain recommendations on how to optimize your website

### Early Hints

Preload assets before the HTML response arrives. [Learn more about Early Hints](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/speed/optimization/content/early-hints/).

* **Asset preloading** \- Send `103 Early Hints` responses so browsers start fetching assets before the full HTML arrives
