[Bug 1698454] Re: TCP/IP Throughput Limitation

In light of my previous findings I did a dual boot install with 15.10 and 16.04. I put both installs on 4.3.6 mainline kernel and found that 15 was fine and 16 was not. I started looking at installed packages and tried to isolate some packages. After uninstalling several and rebooting I found

[Bug 1698454] [NEW] TCP/IP Throughput Limitation

Public bug reported: I'm having a severe TCP receive problem with a new Ubuntu 16 server and an Intel 82599ES 10-Gigabit SFP+ (X520 series card) when a windows 10 machine is used to send the data. The receive performance is 1Gb to 2Gb steady using iperf single stream, while send is 9.42Gb. Here
