When the user sets the creation rate, the level may be directly set, for example, high, medium, low, etc., and of course, a specific numerical value of the creation rate may also be set, and the RBD layer determines the level corresponding to the creation rate based on the correspondence between each level and the rate interval. Each level corresponds to a different number of threads, the higher the level, the greater the number of threads.
