Assigning prioritized rebuild resources optimally

A computing device of a group of computing devices of a dispersed storage network (DSN), the computing device comprises:

• an interface;
• a local memory;
• and
• a processing module operably coupled to the interface and the local memory, wherein the processing module functions to:
• determine, by a plurality of rebuild modules, to rebuild one or more encoded data slices to a DSN memory unit;
• determine, by at least one of the plurality of rebuild modules, a rebuild rate of the DSN memory unit;
• determine, based on the rebuild rate, a rebuild rate status of the DSN memory unit;
• and
• when the rebuild rate status is a high rebuild status, reduce the rebuild rate to the DSN memory unit;
• and
• rebuild, when the rebuild rate is not reduced to zero, the one or more encoded data slices in the DSN memory unit.
