Subject: [PATCH RFC net 0/2] ipv6: Avoid restarting fib6_lookup() for RTF_CACHE hit
Date: Fri, 3 Oct 2014 15:12:10 -0700 [thread overview]
Message-ID: <1412374332-26657-1-git-send-email-kafai@fb.com> (raw)
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
