The rapid development of mobile Internet, the birth of many apps, but also many apps due to the inability to obtain real-time data resulting in operational decision-making mistakes and die in swaddling. In order to enable developers to control the development of the application in real time, there are companies specializing in the application of statistical Analysis Services at home and abroad, developers n

. Typically, a graph of throughput vs load is generated in the performance analysis to explore the capacity limits of the network hosting business. The load scalar here is used as a separate variable, and as the simulation input is changed in each simulation, the throughput is recorded as a result scalar as a non-independent variable.The source of the scalar result is the active output of the call Op_stat_write_scalar () function in the process code.T
