What is CDN?
A CDN serves static content from nodes closer to visitors, reducing latency and load on the origin server.
Definition
A CDN serves static content from nodes closer to visitors, reducing latency and load on the origin server.
What does it mean in practice?
For websites and online services, CDN affects response time, reliability, resource usage and the quality of the network path.
A practical Hostilla.pl example
Measure the same URL from a repeatable location before and after a change. CDN should be correlated with server response time, application logs, resource use, caching and the network path rather than judged from one browser refresh.
What should you check?
- the exact URL, device, location and test time
- a baseline for response time and page metrics
- PHP, database, disk, cache and resource usage
- one controlled change followed by the same test
