Roon RAAT and "An audio file is loading slowly"

[mdconnelly]

I use two HP ProCurve J9085A switches (6 meters apart) linked with Gig copper and vlan trunking between them. My router is a Palo Alto PA-220 firewall (with a Cisco DOCSIS cable modem in front), but nothing is directly connected to the firewall other than the "inside" interface. All layer two is handled by the two switches and a Dlink 505 wireless unit in bridge mode for the Android remotes.

The two switches have each 24 100BASE-T ports, two 1000BASE-T and two SFP slots (that are not used at the moment). The switches are completely silent and fan-less. Roon Core is connected to one switch while the Devialet amp to the other, both on 100Mbps ports. So there is a gigabit link between the switches, but what matters seems to be the ports devices are connected to. Ethernet cables are cheap Cat5 with no shielding.

I suspect that if the transfer from Roonserver to Devialet is 100mbps, all will work.   I've yet to hear from anyone that is successfully playing Roon RAAT to Devialet at gigabit speed with hi-res content, yet Devialet says it works for them.

Tomorrow I will receive a 100mbps switch.  I'll switch my PC running Roonserver back to gigabit speeds to router and put the 100 mpbs switch in front of the Devialet which should mean 100 mbps between router and Devialet.    We'll see if that works.  

Sure wish Roon Labs would weigh in...
