Message-ID: <1412232548-29551-1-git-send-email-kafai@fb.com> Date: Wed, 1 Oct 2014 23:49:06 -0700 From: Martin KaFai Lau <kafai@...com> To: <netdev@...r.kernel.org> CC: <kafai@...com> Subject: [RFC net 0/2] ipv6: Avoid restaring fib6_lookup() for RTF_CACHE hit I am trying to understand why there is a need to restart fib6_lookup() after getting rt with RTF_CACHE. I have adapted the davem's udpflood test (https://git.kernel.org/pub/scm/linux/kernel/git/davem/net_test_tools.git) to support IPv6 and here is the result: #root > time ./udpflood -l 20000000 -c 250 2401:db00:face:face::2 Before: real 0m33.224s user 0m2.941s sys 0m30.232s After: real 0m31.517s user 0m2.938s sys 0m28.536s -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
