Finastra Performance Tester Interview Questions, Process, and Tips

Deadlock is a situation where two or more processes are unable to proceed because each is waiting for the other to release a resource.

• Deadlock occurs when two or more processes are stuck in a circular dependency, where each process is waiting for a resource held by another process.

• It can happen in multi-threaded or multi-process environments.

• Deadlock can be caused by resource contention, improper synchronization, or pr...read more

Performance testing focuses on evaluating the speed, responsiveness, and stability of a system, while performance engineering involves designing and optimizing the system for optimal performance.

• Performance testing is the process of testing the performance characteristics of a system under specific conditions.

• Performance engineering is the proactive approach of designing, building, and optimizing a system for optimal p...read more

Memory leak is a software issue where allocated memory is not released, leading to memory consumption and performance degradation.

• Memory leak occurs when a program fails to deallocate memory that is no longer needed.

• It can happen due to programming errors like not freeing allocated memory or losing references to it.

• Memory leaks can cause the program to consume excessive memory, leading to performance issues and crashes...read more

Performance bottleneck can occur in various areas of an application.

• Database queries and indexing

• Network latency and bandwidth

• CPU and memory usage

• Code inefficiencies and poor algorithms
