| Summary: | Nowadays, non-functional testing has a great impact on the real-time environment. Non-functional testing helps to analyze the performance of the application on both server and client. Load testing attempts to cause the system under test to respond incorrectly in a situation that differs from its normal operation, but rarely encountered in real world use. Examples include providing abnormal inputs to the software or placing real-time software under unexpectedly high loads. High loads are induced over the application to test the performance, but there is a possibility that particular pattern of the low load could also induce load on a real-time system. For example, repeatedly making a request to the system every 11 seconds might cause a fault if the system transitions to standby state after 10 seconds of inactivity. The primary aim of this study is to find out various low load input patterns affecting the software, rather than simply high load inputs. A quasi-experiment was chosen as a research method for this study. Performance testing was performed on the web application with the help of a tool called HP load runner. A comparison was made between low load and high load patterns to analyze the performance of the application and to identify bottlenecks under different load.
