This seems snappy from the US but I doubt someone in say NZ will have a good experience. Going back and forth between the client and the server on every interaction can result in terrible UX. Users will be happy waiting 1-2 seconds after submitting a form but waiting that much to switch a tab is not gonna fly. Plus there's internet weather etc which might result in unpredictable latencies over long distances. Yes, yo…
Which means its gonna be the same thing if you try to render on the client, since you still need a round trip for data...
