![]() Bottlenecking - This occurs when data flow is interrupted or halted because there is not enough capacity to handle the workload.O ther performance problems can be observed: Speed issues - slow responses and long load times for example - often are observed and addressed. Most Common Problems Observed in Performance TestingÄuring performance testing of software, developers are looking for performance symptoms and issues. It is also known as flood testing because the test floods the system with data. Volume testing determines how efficiently software performs with large projected amounts of data. Also, the workload may stay at the same level while resources such as CPUs and memory are changed. This can be determined by gradually adding to the user load or data volume while monitoring system performance. Scalability testing is used to determine if software is effectively handling increasing workloads. The memory leak can impair system performance or cause it to fail.) Scalability Testing (A memory leak occurs when a system fails to release discarded memory. The goal of endurance testing is to check for system problems such as memory leaks. Endurance TestingÄ®ndurance testing - also known as soak testing - is an evaluation of how software performs with a normal workload over an extended amount of time. The workload is beyond normal expectations for short amounts of time. Spike testing is a type of stress testing that evaluates software performance when workloads are substantially increased quickly and repeatedly. At what point does software fail, and how does the software recover from failure? Spike Testing The goal of stress testing is to measure the software stability. The software is given more users or transactions that can be handled. Unlike load testing, stress testing - also known as fatigue testing - is meant to measure system performance outside of the parameters of normal working conditions. That workload falls within the parameters of normal working conditions. The system is monitored to measure response time and system staying power as workload increases. That workload could mean concurrent users or transactions. Load testing measures system performance as the workload increases.
