Well, doing local network flent RRUL stress tests indicated that my omnia (at that time with TOS4/Openwrt18) only allowed up to 500/500 Mbps shaping with bi directionally saturating traffic with full MTU-sized packets. So I undirectional CAKE at 1Gbps can work, but under full load, I did not manage that, what did I wrong?
