Have you ever conducted system testing under high load?

Yes, I have conducted system testing under high load. This usually includes:

• Creating scenarios that simulate a large number of users or requests.
• Using load testing tools (e.g., JMeter, Locust).
• Monitoring system performance: response time, resource usage (CPU, memory, network).
• Analyzing results to identify bottlenecks and potential issues.

For example, for a web application, I could set up a test that simultaneously sends 1000 requests per second to see how the server handles the load and whether it crashes.
