Roon RAAT and "An audio file is loading slowly"

[ogs]

I believe AIR is still UDP while RAAT is TCP. TCP has much higher payload than UDP so for the same track playing one would observe higher bandwidth use with TCP. It's been a while since I looked at the difference in bandwidth use between the two, but I think TCP showed more than 50% higher bandwidth use than UDP. 100mbps is enough by a wide margin by the way - 192kHz material is less than 15mbps using RAAT (TCP). 1000BaseT and 100BaseT are quite different as I think the two are running different protocol stacks within the same hardware. The obvious difference is four pair use for gigabit vs two pairs for 100BaseT, but there are other differences too even if 1000BaseT is based on the 100BaseT spec.
