Network cloud performance data storage method and device and electronic equipment

The invention provides a network cloud performance data storage method and device and electronic equipment, and the method comprises the steps: obtaining a to-be-stored performance data file, and determining a file identifier of the to-be-stored performance data file; on the basis of the file identifier of the to-be-stored performance data file and the file identifier in the cache library, when it is determined that a target data file is stored in the target database, after the target data file is deleted from the target database, the to-be-stored performance data file is stored in the target database; and storing the to-be-stored performance data file into the target database and storing the file identifier of the to-be-stored performance data file into the cache library under the condition of determining that the target data file does not exist in the target database based on the file identifier of the to-be-stored performance data file and the file identifier in the cache library. According to the method,
