The invention relates to a distributed storage performance test method and system in a broadcast and television service scene, and the method comprises the following steps: setting an adaptive test model according to the broadcast and television service scene, and compiling related test data; determining the configuration of the distributed storage system in a broadcast and television service scene; establishing a test environment according to the configuration, wherein the test environment comprises a distributed storage system, a network system and a client system; creating a test script according to the test data; executing the test script, testing by adopting a test tool, and recording a test result. The system comprises a test model setting module, a distributed storage system configuration module, a test environment establishment module, a test script creation module and a test module. The method comprises the following steps: simulating a read-write operation of a user accordingto a radio and television service scene test model, generating a test file, and testing by using a test tool; unnecessary performance tuning time in the test process is reduced, and an optimal test result is directly obtained.
