NDB Cluster dump import slow

we just built a new NDB Cluster on physical hardware to replace our virtual cluster. Every night we create a dump file of all the databases on the production system. I am trying to import these into the new cluster. Unfortunately it is unbelievable slow. If it doesn't fail, 17GB will take around 45 hours. The cluster consists of 2 datanodes (16 cores and 178GB RAM each), 2 apinodes (16 cores and 48GB each) and 2 management nodes (2 cores and 24GB RAM each). All nodes are connected through a separate 10GBit network.
I am a bit confused why it is performing so badly, can someone help me? What am I missing?

Kind Regards,
