I have backport the "Under Review" patches into Xenial 4.4.0-49 to test, here are the numbers :
# uname -a Linux <HOSTNAME> 4.4.0-49-generic #70hf121102v20161124b2-Ubuntu SMP Fri Nov 25 02:34:36 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux # iptables -F # time (./list-addrs 3000 | xargs -n1 iptables -A FORWARD -j ACCEPT -s) real 0m5.661s user 0m0.096s sys 0m0.452s So the patches have positive impact on mainline kernel and Xenial Ubuntu kernel. Once the patches are approved, I will submit it to the kernel team.
