Who was responsible for load testing? What tools were used for load testing?

For load testing, I used tools such as:

• JMeter — convenient for creating complex scenarios with a large number of requests.
• Locust — written in Python, allows scripting load testing scenarios programmatically.
• k6 — a modern tool with JavaScript support, well integrated into CI/CD.

In the context of Go projects, k6 is often used due to the simplicity of writing tests and the ability to integrate with Go services. It is important to model real usage scenarios and monitor performance metrics to identify bottlenecks.
