I know this has been reported (and fixed) earlier but in our setup with
Ubuntu 14.04 and 10 Gbps links, using something like Iperf with a single
flow we max out at a 3-4 Gbps and see 100% CPU utilization on one of the
cores. Is this expected? If not, are there configuration parameters we need
to adjust? Any particular system info needed to know what is happening? Any
suggestions or pointers to where we can find more information is much
appreciated.

Best,

Mohammad
