this is with cero or last weekend's build?

So column 7 (ipv4) and column 8 (ipv6) are larger than columns 9 (ipv4) and 10 (ipv6) showing that dual egress instead of egress and ingress effective upload increases by < 10 Mbps (while download and latency stay unaffected). That is not bad, but also does not look like the IFB is the cost driver in sqm-scripts, or does it? Also as a corollary of the data I would say, my old interpretation that we hit a limit at ~70Mbps combined traffic might not be correct in that ingress and egress might carry slightly different costs, but then thins difference is not going to make a wndr punch way above its weight…
