Performance Engineering Interview Questions And Answers
Q) What is performance testing?
ANSWER: Performance is tested for quality assurance. software applications involve testing to ensure that the software performs well under expected workloads.
Characteristics of performance testing include
- Speed: This determines whether the application responds quickly.
- Scalability: It determines the maximum user load that the software application can handle.
- Stability: It determines whether the application is stable under various loads.
Q) What is the need to choose Performance?
ANSWER: To evaluate performance based on applications, we need performance testing. These evaluations are performed under certain stress and load conditions. Response time relative to user activity is commonly used to measure performance testing. The entire system is tested under high pressure and load conditions
Q) Mention different types of Performance Testing?
ANSWER:
- Load testing
- Stress testing
- Endurance testing
- Spike testing
- Volume testing
- Scalability testing
Q) Mention the Tools used for Performance Testing?
ANSWER:
- QA Load (Compuware)
- Load Runner (HP)
- Web load (Rad view)
- Rational performance tester (IBM)
- Silk performer (Borland)
Q) What are the common performance bottlenecks?
ANSWER:
- CPU Utilization
- Memory Utilization
- Networking Utilization
- S limitation
- Disk Usage
Q) Mention the important parameters considered for performance testing?
ANSWER:
- Response time
- CPU interruption per second
- Committed memory
- Memory usage
- Processor usage
- Bandwidth
- Memory pages
- Network output queue length
- Thread counts
- Top waits, etc.
Q) What are the factors for selecting Performance Testing Tools?
ANSWER:
- Customer preference tool
- Availability of license within customer machine
- Availability of test environment
- Additional protocol support
- License cost
- Efficiency of tool
- User options for testing
- Vendor support
Q) What is the difference between Performance Testing & Functional Testing?
ANSWER:
| Performance Testing | Functional Testing |
|
|
Q) What is performance in performance testing?
ANSWER: Throughput refers to the amount of data sent to the server in response to a client request over a specified period of time. It is calculated in terms of requests per second, calls per day, reports per year, hits per second, etc. The performance of the application depends on the performance value, the higher the performance value – the higher the performance of the application.
Q) What are the common mistakes that are done during performance testing?
ANSWER:
- Confusion on the definite of Concurrent users
- A significant difference between the test and production environment
- Network bandwidth not stimulated
- Underestimating performance testing schedules
- Incorrect extrapolation of pilots
- Inappropriate base-lining of configurations.
- Direct jump to multi-user tests
- Test results not validated
- unknown workload details
- Too small run duration
- Lacking long-duration sustainability test
Q) What is Neo load?
ANSWER: Neo Load is a tool that measures the performance of a web or mobile application. It is a stress and load-testing tool. It provides programmatic solutions to developers to improve performance before the application goes into production. It is available in French and English. It is a type of load-testing equipment
Q) What are the Correlate graph and overlay graph?
ANSWER:
- Correlate Graph: Y-axis where both graphs are plotted against each herb. After this, the Y-axis of the active graph is treated as the X-axis of the linked graph. Henceforth, the graph connected to the Y-axis of that graph becomes the Y-axis.
- Overlay Graph: Draw two graphs with the same x-axis. The left Y-axis in the attached graph shows the current value of the graph. The right Y-axis shows the Y-axis value of the linked graph.
Q) What are spike testing and soak testing?
ANSWER:
- Spike testing: A spike test is a change in usage when there is a sudden increase or decrease in the number of users.
- Soak testing: Shock testing is used to find out the behavior of the application when we use loads for a long time or for a long time. stability (character of the application) and response time of the application is determined by the process.
Q) What do you know about distributed testing?
ANSWER: Distributed testing is defined as a process that enables application testing to be performed across a number of users who have simultaneous access to the application.

ANSWER:
- Application response time for the intended number of users-
- Maximum load resistance capacity of the application.
- The ability of the application under test to handle a specified number of transactions.
- Stability of an application under regular and unexpected user load.
- Ensuring proper response time to users in production.
Q) How to perform Spike Testing in JMeter?
ANSWER: In JMeter, spike testing can be achieved using the Synchronizing Timer. Threads are jammed by synchronizing a timer until a certain number of threads are successfully blocked, then releasing them simultaneously causes a large instantaneous load.
Q) What is the difference between JMeter and SOAPUI?
