Yes there is a performance overhead although this should be negligible on Series 4/4S appliances, I suppose the question is, do you need to secure transmissions between the appliances? if so then you require the SSL option to be enabled (isn't by default).

The impact would entirely depend on configuration,hardware,software version and throughput (log/packet??), without understanding this it is not possible to specify the exact performance hit. As the chattiest communication is between the Decoder and Concentrator then, yes this is where the highest impact would be.
