Why it helps the client
- Cuts latency by an average of ~30% by avoiding congested public Internet routes.
- More consistent performance — fewer slow outliers for distant users.
- Higher cache hit ratios and less origin load through Tiered Cache.
- Works for dynamic, non-cacheable traffic that a CDN alone can't accelerate.
Why they'd want it
- A single toggle that makes the whole site faster — no code, no re-architecture.
- Measurable latency wins, backed by per-request analytics.
- Speed for APIs and logged-in pages, not just static assets.

Questions clients ask
Tap a question to reveal the answer to sayIs the ~30% latency reduction real, or a best case?›
It's an average across Cloudflare's customer base; wins are biggest for globally distributed users and dynamic content, smaller when users are already close. The ArgoArgoCloudflare's smart-routing product that sends traffic over the fastest paths on our private backbone. analytics show your actual measured reduction, so it isn't a leap of faith.
Isn't this just a CDN by another name?›
No. A CDNCDNContent Delivery Network — a worldwide set of servers that keep copies of your content close to users so pages load faster. caches static content near users.

They're complementary.
What does it cost?›
Usage-based: a small monthly base plus per-GB of routed traffic. For most customers the performance gain and originoriginYour own web server or host where your website actually lives. Cloudflare sits in front of it. savings outweigh it, and we can estimate from your current bandwidth.
Any risk to turning it on?›
It's a toggle you can disable instantly, and it doesn't change your app — only the network path. Worst case you switch it off, but the analytics almost always justify keeping it on.
Does it help if our origin is in only one region?›
Especially then — a single-region originoriginYour own web server or host where your website actually lives. Cloudflare sits in front of it. is exactly where distant users suffer, and smart routing plus Tiered CacheTiered CacheOrganizing Cloudflare data centers into layers so fewer requests ever reach your origin. shrink that penalty the most.
