You're welcome, docder.
Just a quick objective, numerical update. In the past few months I've used Roon with a typical router setup and have had to periodically restart the BDP-1 either because I was going out, or there were thunderstorms, or an Error code due to voltage spike. Whenever the BDP-1 restarts, by habit I always disable USB mount and Samba server options, leaving only Roon Ready checked under the Services Tab at the bottom of Manic Moose page.
Within an hour after booting, I find the BDP-1's CPU% come to a stable percentage with only occasional spike increases. In the past 6 months, that percentage was always around 14-15%.
In the past 3 days that I've been using the bridged ethernet configuration, I've had to restart a total of 3 times due to lightning, and an error code. As before, I disabled USB mount and Samba server each time. In all of these instances after letting the BDP-1 settle down, I've found that the CPU% is consistently at 19-20% and spikes well into high 20's and low 30's at times. I'm not sure why there's a difference all of a sudden, but it's there consistently. I'm not sure why this may be the case, but wonder if either Roon's and/or BDP-1 processes have changed in some aspect.
