Subject: How fast can your 10G go?
Date: Tue, 19 May 2009 09:05:40 -0700 [thread overview]
Message-ID: <4A12D8D4.2070303@candelatech.com> (raw)
I've been running some tests on a new Nehalem based system
with a 2 port pci-e x8 10G NIC (ixgbe driver).
When using pktgen, max I can get is about 5.6Gbps tx + rx on both ports. This is
about 22Gbps across the backplane, so I don't mean to complain :)
However, I'm curious if anyone has gotten any better performance on
some other system? In particular, it seems that my system is bound by
the bus and/or the NIC. Would I need to find something like a x16 slot
to have a chance at 10Gbps bi-directional on 2 ports?
Thanks,
Ben
