What is VPN?
A VPN creates an encrypted tunnel to a network or service.
Definition
A VPN creates an encrypted tunnel to a network or service.
What does it mean in practice?
For websites and online services, VPN 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. VPN 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
