Could you explain what is meant by load testing?

Load testing is a type of software testing where the behavior of the system is checked under high load, close to or exceeding the expected maximum in real-world conditions.

The goal is to determine how the system performs with a large number of simultaneous users, requests, or operations, identify bottlenecks, performance issues, and stability problems.

Example: if you have a web application, load testing will help you understand whether it can handle 1000 concurrent users without failures or delays.

In C#, tools like Visual Studio Load Test, JMeter, or specialized libraries for creating load scenarios are often used for such purposes.
