Performance test method of stream processing system and related device

The invention discloses a performance test method for a stream processing system, and the method comprises: carrying out the random load transmission processing according to a plurality of obtained configuration files of different test scenes and different variables and corresponding message queues, so as to enable the stream processing system to load different random load data; controlling a flowprocessing system to perform flow processing on the corresponding random load data according to each configuration file to obtain a corresponding flow processing result; and performing statistical analysis processing on all stream processing results to obtain a test result. Different random load data are loaded through the stream processing system, then stream processing is carried out accordingto the configuration file to obtain a stream processing result, and finally statistical analysis is carried out to obtain a test result, so that the influence of a specific service reading test process is avoided, unified test
