XDP – eXpress Data Path

Status: Linux perf improvements ● ● ● Linux performance, recent improvements ● approx past 2 years: Lowest TX layer (single core, pktgen): ● Started at: 4 Mpps → 14.8 Mpps (← max 10G wirespeed) Lowest RX layer (single core): ● Started at: 6.4 Mpps → 12 Mpps (still experimental) ● ● XDP: drop 20Mpps (looks like HW limit) IPv4-forwarding ● Single core: 1 Mpps → 2 Mpps → (experiment) 2.5Mpps ● ● Multi core : 6 Mpps → 12 Mpps (RHEL7.2 benchmark) XDP single core TX-bounce fwd: 10Mpps 22/23 XDP – eXpress Data Path
