Genpact Performance Engineer Interview Questions, Process, and Tips

PTLC stands for Performance Testing Life Cycle, which is a process followed in performance testing to ensure the performance of a system.

• PTLC involves planning, preparation, execution, and analysis of performance tests.

• It includes defining performance goals, creating test scenarios, executing tests, and analyzing results.

• PTLC helps in identifying performance bottlenecks and optimizing system performance.

• Example: In PTL...read more

Python script to capture system resources

• Use psutil library to access system resources

• Collect CPU, memory, disk, and network usage data

• Display the captured resources in a readable format

Network bandwidth constraint in testing refers to limitations on the amount of data that can be transmitted over a network during testing.

• Network bandwidth constraint can impact the performance of an application or system being tested.

• It can lead to slow response times, timeouts, or even failures during testing.

• Examples of network bandwidth constraints include limited bandwidth on a shared network, network congestion, ...read more

Timers in JMeter are used to simulate real user behavior by adding delays between requests.

• Timers help in controlling the load on the server by adding delays between requests.

• They can be used to simulate realistic user behavior by adding random or constant delays.

• Examples of timers in JMeter include Constant Timer, Gaussian Random Timer, and Uniform Random Timer.
