The application discloses a performance test method, device and
system, to solve the problems of low
test efficiency, incomplete test results and low accuracy of the existing performance test method. The method comprises: determining a first parameter value dataset corresponding to a
network parameter of a gateway device under the condition that a
wireless signal is transmitted between the gateway device and a
transceiver, the first parameter value dataset comprising a plurality of parameter value subsets, wherein the first parameter value dataset is a parameter value corresponding to the
network parameter under a first test angle; determining whether the
network parameter of the gateway device meets a preset adjustment condition according to a first test result corresponding to the first parameter value dataset and / or the first parameter value subset; and adjusting the network parameter according to a second parameter value dataset if the network parameter meets the preset adjustment condition. This technical solution improves the efficiency of
network performance testing and ensures that the final test results can more comprehensively and accurately reflect the performance of the gateway device.
