Subject: Dropping Packets in 2.6.17
Date: Thu, 22 Jun 2006 04:31:47 -0700 (PDT)	[thread overview]
Message-ID: <20060622113147.3496.qmail@web33304.mail.mud.yahoo.com> (raw)

I'm trying to make a case for using linux as a
network appliance, but I can't find any
combination of settings that will keep it from
dropping packets at an unacceptably high rate.
The test system is a 1.8Ghz Opteron with intel
gigE cards running 2.6.17. I'm passing about 70K
pps through the box, which is a light load, but
userland activities (such as building a kernel)
cause it to lose packets, even with backlog set
to 20000. I had the same problem with 2.6.12 and
abandoned the effort. Has anything been done
since to give priority to networking? You can't
have a network appliance drop packets when some
application is gathering stats or a user is
looking at a graph. What tunings are available?
