Hi Guido. The docs section you referenced is for RiakCS. We do recommend a substantially higher value for zdbbl when using RiakCS because the object data being stored is divided into 1MB chunks which is still a relatively large object size for Riak to handle. Riak used by itself may not need the value to be that large, but it may benefit depending on the size of objects you are storing. If you do decide to increase the value beyond 16384, just proceed with caution and make sure you have enough memory to support the increased setting.
