Q. 26 What are the common bottlenecks identified during the performance test?
Ans: The possible bottlenecks are:
Ans: Performance improvement recommendation always depends on the nature of the bottleneck. If there is any network related issue then you can recommend to optimize the latency and bandwidth. At the database level, verify all indexes and sequences by running profilers. You may also recommend to optimize the database queries. At the App server level, run profilers for finding the memory leaks in the application. At the web server level, you can use monitors and optimize the throughput and other related metrics of the server.
Q. 28 How do you identify the performance bottlenecks?
Ans: The Performance Bottlenecks can be detected by using monitoring and profiling tools. These tools should monitor the application server, web server, database server and network. These tools help in finding out the troubled area during the test which causes increased response time.
Q. 29 Do you know any agentless server monitoring tool?
Ans: Micro Focus SiteScope
Q. 30 Do you know any profiling tool?
Ans: Micro Focus Diagnostics, DynaTrace
