A little more information about your cluster might help.

Nowadays everything will be able to saturize 1Gbps links.

Better you add faster hardware to your cluster.

Cheapest solution will be connecting 2 nodes directly with 2 USB3 
ethernet devices and a cable. 2.5 or 5 Gbps just for cluster 
communication or/and replication will make a difference.

10Gbps cards and switches wound be even better.

Dual 40 Gbps connections probably may be overkill :-)

It all depends on what you are doing.
