It creates a cgroup to use for testing and load a BPF program to limit egress bandwidht. It then uses iperf3 or netperf to create loads. The output is the goodput in Mbps (unless -D is used). It can work on a single host using loopback or among two hosts (with netperf). When using loopback, it is recommended to also introduce a delay of at least 1ms (-d=1), otherwise the assigned bandwidth is likely to be underutilized.
