How can performance testing help identify potential bottlenecks in a system?
What is a performance bottleneck? A bottleneck refers to a specific point wherein a single component limits the capacity of an application or computer system. The component whether it is in the hardware infrastructure or the software stack can restrict the process flow. The system's overall capability is limited, which, in turn, leads to problems such as high levels of end-user frustration, long load times and increased downtime. Following are the key tactics through which performance testing can help in identifying potential bottlenecks: 1. Utilizing the CPU: Performance bottlenecks can happen because of the usage of the CPU. This generally happens when the processor is not able to perform the requests asked of it. The system can be overloaded by too many processing requests, which, in turn, can cause slowdowns. CPUs handle information requests, run database inquiries, execute programs and process data effectively. When the data that can be processed is less than the data tha
