(1/8394560-1/8179480)*10^9 = -3.13239 ns But was the xdp_redirect_map code-path affected from patch 1/1? (1/8412754-1/8394560)*10^9 = -0.2576 ns It doesn't look like any performance regression to xdp_redirect_map from these code changes :-) -- Best regards, Jesper Dangaard Brouer MSc.CS, Principal Kernel Engineer at Red Hat LinkedIn: http://www.linkedin.com/in/brouer
