RE: If the application response time is increasing 10 ...
Please be more specific in your question.
What else is happening apart from the increase in TRT? Is the response time increasing as the number of Vusers are increasing? Is it increasing after every subsequest Iteration?
There can be several reasons but its hard to comment without having a clear picture.
RE: If the application response time is increasing 10 to 15 sec, this is the problem?How we can solve this?
If the Response Time is increasing frequently there may be enough load on the page. Performance tester should analyze the test result graph and find out where it needs to Tuning. Tuning is the best solution.
RE: If the application response time is increasing 10 to 15 sec, this is the problem?How we can solve this?
For most applications if the response time increases by 10 to 15 seconds there is definitely a problem. Many users will abandon a page if it doesn't render by 10 seconds. First make sure the time to render performance metric is clearly mentioned in the technical specification. If not then take this up with the Project Manager. Time permitting the tester can review image sizes for example to determine whether new images have been introduced to the pages that have not been optimized for load times. Beyond that it is the responsibility of the tester to report the problem not solve it. Given time constraints the tester should simply author a defect report and pass the responsiblity of solving the issue to the developers.
