Performance test method and device, and storage medium

The embodiment of the invention provides a performance test method and device, and a storage medium, relates to a data analysis technology, and can improve the accuracy of performance changes, of an application, caused by applying a preset function to an experimental region. The specific scheme comprises the following steps: obtaining a first experimental index and a first reference index of an application program; extracting a plurality of experimental features influencing the first experimental index and a plurality of reference features influencing the first reference index; according to the first experimental index and the corresponding experimental feature, and the first reference index and the corresponding reference features, determining combination information corresponding to a plurality of reference regions; obtaining a second experimental index and a second reference index of the application program; according to the first experimental index, the first reference index, the second experimental index
