Test CDN Performance And Caching
A CDN checker to measure global CDN speed.
CDN performance test
Check if your CDN is working correctly
Are server responses served from a CDN? Are responses cached at the edge? Do visitors connect to their closest CDN region?
Understand global visitor experience
View how CDN speed varies across the world and whether delays come from latency or poor server response time.
Check CDN cache status
What is a CDN cache?
For best response times, content delivery networks can cache website content at a location close to the visitor. Our tool can tell you whether responses are served from the cache or generated dynamically.
What causes cache hits and misses?
To get a cache hit, two things need to happen: caching for this resource has to be enabled, and the resource has to have been recently requested from that CDN edge node.

How do CDNs work?
Servers close to your users
Content delivery networks provide global server infrastructure, reducing latency.
Faster websites
Lower latency and improved caching mean your website loads faster for visitors.
