Load testing simulates traffic to see how a site behaves under heavier use.

Definition

Load testing simulates traffic to see how a site behaves under heavier use.

What does it mean in practice?

For websites and online services, Load testing 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. Load testing 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
