Cloud platform network performance test method and system

The invention provides a cloud platform network performance test method and system, which can accurately test the network performance of a cloud platform. The cloud platform network performance test method comprises the following steps: testing network performance difference between a virtual local area network and a virtual extension local area network of a physical machine; when the network performance difference is smaller than a preset performance difference, creating an environment required by the cloud server in the platform environment; creating a plurality of groups of cloud servers with different numbers of network card queues on the same host machine to test the network performance between the cloud physical hosts of the same computing node to obtain a plurality of groups of first test results; creating a plurality of groups of cloud servers with different network card queue numbers on different host machines to test network performance among different computing node cloud physical hosts to obtain a
