Give a simple real-life example of a bottleneck.
Like a narrow doorway in a busy hallway that slows down people passing through, a bottleneck slows down data or tasks in software.

What is the main goal of performance testing?
✗ Incorrect
Performance testing aims to find slow points or bottlenecks that affect system speed.
Which of these is a sign of a bottleneck?
✗ Incorrect
System crashes or slowdowns under heavy use often indicate bottlenecks.
When should bottlenecks ideally be fixed?
✗ Incorrect
Fixing bottlenecks before release ensures better performance and user satisfaction.
What does performance testing simulate?
✗ Incorrect
Performance testing simulates many users or tasks to check system behavior under load.
Which analogy best describes a bottleneck?
✗ Incorrect
A bottleneck is like a narrow doorway that slows down the flow of people or data.
Explain in your own words why performance testing helps prevent bottlenecks.
Think about how testing under pressure shows where the system slows down.
