What is lazy loading?
Lazy loading means images, iframes, or other elements are delayed in loading only as the user approaches them on the page. Reduces the initial page size and can improve loading speed. On Hostilla, this can be implemented in a theme, a cache plugin, or directly in HTML.

What does it mean in practice?
For websites and online services, lazy loading 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. lazy loading 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
