Jay,
It should be expected of the LRU restore process to have an impact on the cluster. LRU_restore causes a lot of IO activity especially for large bufferpools. This would cause excessive load on one of the nodes, and inadvertently cause problems to the cluster because that one node might not be able to keep up with cluster replication during the time LRU_restore is in progress.
