Volume

8. Stability
Is the application stable under
expected and unexpected user loads?
(AKA Robustness)
How do we measure?
Consistency
Reliability
Stress

9. What is Performance Testing?
Speed Load testing
Scalabilit -> Stress testing
y Endurance testing
Stability

10. Load Testing
Progressively
Concurrent users
Response time

11. Stress Testing
Upper limits
“That’ll never happen in
production”
….but it does 

12. Endurance Testing
Continuous expected load
Tests ran long time
Emergent behaviors

13. How to conduct Performance
Tests?
Performance key points
Performance Test Plan (how much load?)
Choose tools

14. Performance key points
Concurrency/Throughput (Transaction Rate)
Server Response Time
Server Resources Monitoring

15. Performance Test Plan
(how much load?)
Transactions
Schema
Three situations

16. Tools – 2 case studies
