I'm looking at an iperf issue running over ixgbe on linux
on a sparc T5-2 platform (64 cpu) where we cannot get to line-speed
(peaks at 3 Gbps on a 10Gbps link) and I'm trying to get to the bottom
of this.
I've run iperf

1. lockstat and perf report that iommu-lock is the hot-lock (in a typical
instance, I get about 21M contentions out of 27M acquisitions, 25 us

If you have ATR disabled we will spread the flows to different queues based on
their RSS hash. Could it be that you are only seeing one flow, in which case

Thanks,

All this may be true, but it would also be true for Solaris, which
manages to do line-speed (for the exact same setup), so there must be
some other bottleneck going on?

I'm not running Ubuntu, I'm looking at the 3.16.4-based kernel
source in our local LXR database reportedly from the Ubuntu
14.10 linux-source package. IIRC, I ran 'make modules_prepare'
using the 14.10 kernel config file which is supposed to generate
the appropriate header files
No, I generate traffic with random src ip and src port (but same dst ip
and dst port). So I have many flows.
