Situation
Solution
Step1. Summary report of 80 running users on Windows XP System
Picture 1 Summary Report
We can see from the picture all the transactions are successful, so we can believe that we can trust the test result.
Step2. Running Vusers – Average Transaction Response
Picture 2 Running Vusers – Average Transaction Response
From picture2, we can see that when the number of the users increases from 0 to20, the time of transactions is very stabilization. When the number of the Vusers increase from 20 to 125 the time of the transactions increases quickly. We also can see that the transaction "Lifepiece" has nearly no impact on the system. The response time of "LoadSocialNetwork" and "Login" are always very long especially "Loading SocialNetwork".
So we can conclude that:
- 20 Vusers is the inflexion of the system.
- The transaction "Loading SocialNetwork" is the worst transaction.
- When the number of Vusers is 120, the response time become larger than 10.
Step3. Transaction Response Time (Percentile)
Picture 3 Transaction Response Time (Percentile)
We can see from the picture the response time of all the transactions are between 0 and 14, this is acceptable for the users.
Step4. Windows Resources – Running Vusers
Picture 4 Windows Resources – Running Vusers
We can see from the picture that when the number of the Vusers is 110, the CPU of the application server has arrived 75%.
Step5. Analysis of testing resultsThrough observing and analyzing above results, we can conclude that the CPU of the application server is the bottleneck of the system. And it is one of the reasons why the time of the transactions becomes long.
