Câu trả lời Name most common problems observed in performance testing
Common problems observed in performance testing include:
Long Load Time: This refers to the initial time it takes for an application to start. Ideally, load time should be kept to a minimum to avoid losing user interest[1][2].
Poor Response Time: This is the time taken by an application to respond to user inputs. Slow response times can frustrate users and lead them to abandon the application[1][2].
Poor Scalability: This occurs when a software application cannot handle the expected number of users or does not accommodate a wide enough range of users. Scalability issues can make the application unavailable to some users during peak times[1][2].
Bottlenecking: Bottlenecks are obstructions in the system that degrade overall performance. They can be caused by coding errors or hardware issues, leading to decreased throughput under certain loads. Common bottlenecks include high CPU utilization, memory utilization, network utilization, operating system limitations, and disk usage[1][2][6].
High Memory Utilization: Applications that are not optimized for efficient memory use can consume excessive system resources, leading to slow performance and potential system instability[8].
Inefficient Code: Poorly written code can cause numerous performance issues, such as memory leaks and slow processing times[8].
Network Issues: Slow or unstable network connections can significantly impact application performance, especially for web-based applications[8].
Concurrency Issues: Performance can degrade during peak usage if an application cannot handle multiple simultaneous users or operations effectively[8].
Unoptimized UI: Heavy or unoptimized user interfaces can lead to slow rendering times, negatively affecting the...
