Xiaomi BE7200Pro has no measured 5G bottleneck: reading the four-port test

ACWiFi asks whether the Xiaomi BE7200Pro has a “5G” bottleneck, but the measurements discussed here concern the four 2.5G Ethernet ports. I keep that distinction clear so an Ethernet forwarding test is not mistaken for a 5 GHz radio test.¹

Test setup

ACWiFi used IxChariot with the script beginning with High, changing only file_size. The baseline shows that any two-port combination among the four 2.5G ports can sustain full 2.5G in one direction.

With simultaneous bidirectional traffic on all four ports, the combined results stayed above 2300 Mbps in the source's table/screenshots, which did not show a 5G bottleneck between the ports. That is a result under the source's conditions, not a promise that every ISP connection will deliver it.

Router mode and relay mode

The first test used router mode with LAN1 assigned as WAN. ACWiFi also checked relay mode with all four ports transferring at once. For a switch/NAS downstream, the source suggests choosing port 3 or 4 when port 1 or 2 is used as WAN; that is a model-family hint from the port relationship diagram, not a universal rule for every topology.

How I interpret the result

IxChariot and file_size help test port forwarding, but they do not establish long-term thermals, Wi-Fi throughput, every firmware's NAT performance, or behavior with QoS/VPN enabled. I use the result to rule out one port-forwarding bottleneck, then measure my real NAS, VLAN, and WAN workload.

The source records firmware and phone details in other K-point tests; I do not mix those radio results into this Ethernet conclusion. Retail pricing and purchase links are also time-bound.
