By replacing the entire data you trigger the initial-like rendering every time. I don't think it's how it's supposed to work (per Ember) because it does not leverage Glimmer/HtmlBars at all. Ember team is working on improvements for initial rendering but currently it's still 3x slower than it was in Ember 1.12 and I assume it will never be very fast enough for large lists. So I would prefer to have at least fast updates (e.g. on selection). Also keep in mind that there are smartphones with limited cpu and battery - why re-render the entire list?\r\n"}}
