-The `MediaBreadthFirstSeedCount` setting specifies how many media items should be seeded into the cache when doing a breadth-first traversal. The default value is 100.
+When populating the cache on startup the content keys defined by the seeding strategy are processed in batches. The batch size for documents and media can be modified via the `DocumentSeedBatchSize` and `MediaSeedBatchSize` respectively. The default value for both is 100.
