Subject: [Codel] [codel] some numbers on dual 10Gb links
Date: Wed, 09 May 2012 09:32:04 +0200 [thread overview]
Message-ID: <1336548724.21775.7.camel@edumazet-laptop> (raw)
In-Reply-To: <CAA93jw7J2=isAr_4pgiTenOzu1h5ciX6uVPRGx71Ht9_08K=4g@mail.gmail.com>
Some results on my setup (2 fibers at 10Gb), but my remote machine
is a slow quadcore (Q6600). I am waiting net-next compiles on this one
so that I can reverse the test (sender on the slow machine)
10 netperf on one fiber, 10 netperf on the second one.
TC Setup :
