Try these first

1. 1.

   What is response time?

   Hint

   Think about how long you wait after clicking a button.

2. 2.

   Define throughput.

   Hint

   Consider how to measure the efficiency of a system.

3. 3.

   What does response time measure?

   • Time taken to load a web page

   • Time until user interacts

   Hint

5. 5.

   Discuss how you would conduct a load test for a new e-commerce website expecting 500 users at peak hours. List your steps and needed metrics.

   Hint

   Think about user scenarios that are common during peak hours.

6. 6.

   Analyze a scenario where the response time is consistently high (over 2 seconds), but throughput is also high. What could be potential issues?

   Hint

   Consider what could slow down server processing.
