Cloudflare provides a variety of speed improvements by default.

## DNS resolution

When your site is using Cloudflare, your site always benefits from Cloudflare's [lightning-fast DNS resolution](https://blog.cloudflare.com/tag/network-performance-update/).

## Caching

When your DNS records are [proxied](https://developers.cloudflare.com/dns/proxy-status/) through Cloudflare, Cloudflare caches [certain types of resources](https://developers.cloudflare.com/cache/concepts/default-cache-behavior/#default-cached-file-extensions) automatically (which improves application performance).
