I've documented ALL the details here: https://github.com/xdp-project/xdp-project/blob/master/areas/cpumap/cpumap02-optimizations.org I seem to have found that the SKB-list approach is not a performance advantage, which is very surprising. BUT it might still be due to invalid benchmarking, as I found that F27 behind my back is auto-loading iptables-filter modules, which change performance. Thus, I have to redo a lot of the tests... I'm considering removing the SKB-list patch from the patchset, as all other patches show a performance increase/improvement. Then we can merge that, and then I can focus on SKB-list approach in another patchset. BUT as I said above, I might have wrong/invalid measurements... I have to retest before I concluded anything... -- Best regards, Jesper Dangaard Brouer MSc.CS, Principal Kernel Engineer at Red Hat LinkedIn: http://www.linkedin.com/in/brouer
