Loopback UDP pps (~1.25 Mpps @4 threads) is bounded by the kernel loopback path, not by RunPerf. The real measurement needs a real NIC.
Plan: run on the Intel X520 (82599) direct 10G link (SR-IOV VF), target line-rate ~14.88 Mpps @64b, both directions, isolated link. This is the same rig that benchmarks RunX540 tier-1 + Runbound — one hardware pass, three projects.
