Sorry, I think you are thinking of something else. Maybe a railroad crossing (:-))

Joking aside, the https://www.waveform.com/tools/bufferbloat test looks to see if the networking software is working correctly by putting a large load on the network, and then seeing if other streams are affectec by the overload.

The example on the https://libreqos.io/ home page is of * good software delivering 9 and 23 milliseconds down/up latency at full load * bad software delivering 106 and 517 milleseconds latency under load.

It is, in effect, a test for software failure under load

Yeah that sounds like looking for fairness and effectiveness in buffer management in a shared environment. I was thinking of measuring latency of x.

The M1 cards I mentioned was notorious with 1GB (?) buffer and a massively oversubscribed packet processor. Causing extreme jitter.
