Load testing tells you how your website, app, or API behaves before traffic exposes a weak point in public. If users complain about a sluggish site, if performance drops when traffic is high, or if a new feature makes the system lag, load testing gives you evidence before the next release.
Load testing is a branch of software performance testing. It subjects a website or application to simulated workloads that stretch its operational capacity so you can assess performance, reliability, and recovery before slow pages affect user experience, search performance, or conversion.
