# Performance

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/index.md)|[Agent setup](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/agent-setup/)

Accelerate websites and applications with Cloudflare CDN (Content Delivery Network) caching, image optimization, smart routing, load balancing, and web analytics.

* [Cache content globally](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/use-cases/performance/caching/)
* [Optimize images](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/use-cases/performance/image-optimization/)
* [Accelerate connections](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/use-cases/performance/connections/)
* [Optimize web assets](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/use-cases/performance/web-assets/)
* [Balance traffic across origins](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/use-cases/performance/load-balancing/)
* [Monitor performance](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/use-cases/performance/monitoring/)

## Prerequisites

* A [Cloudflare account ↗](https://dash.cloudflare.com/sign-up).
* A domain [added to Cloudflare](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/fundamentals/manage-domains/add-site/) with DNS records proxied through Cloudflare's network. Caching, image optimization, speed optimizations, Argo Smart Routing, and Load Balancing all operate at the edge and require traffic to pass through Cloudflare.
* Web Analytics can be added to any site without a proxied domain by [adding the JavaScript snippet](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/web-analytics/get-started/) to your pages directly.
