Any updates on this? I just noticed that my unbound response times are like 156ms and i have this same setup. I honestly dont know if its an issue, but ive been experiencing odd results with my devices (typically wifi so i doubt its this) connecting to an AP and then no longer getting internet until i toggle wifi on/off/on. That seems more like AP issues than DNS but for every issue i've debugged, im always shocked at how many times it ends up being DNS.
