Perhaps try: sysctl vm.highmem_is_dirtyable=1
Before: 1-3 MB/s write speed, one CPU (25%) wasted on waiting.
After: more than 200 MB/s write speed, 1-2% waiting.
Kernel: 32 Bit 4.4.0-45-generic Ubuntu, 32 GB RAM, SSD

Bugs,
yeah, sorry, I ment lightdm.
killing gui/unity fixes the problem.
Local disk IO is not slow like in your cases, but I still think issues
are related.
Will get to the buttom of this!

Jah,
You mean lightdm, don't you?
If your IO speed with local disk is slow too then I think slow network speed
is just a consequence of a bug like this one.

Jah,
You're welcome.
Your PC1 is under amd64 Linux so I think this issue is not your case.

setting kernel parameter "mem=16384M" did not help
(was set via grub GRUB_CMDLINE_LINUX="mem=16384mb")
killing lightgm resolves the problem and speed jumps to 12mb/s . But
once back in GUI, problem returns.
Tested using Netcat and iperf, LAN speeds peek out at 1.2MB/s

I believe that this issue is a lot more common, but goes unnoticed.
Can reproduce in 14.04.1 LTS on multiple laptops/pc motherboards.

I recently installed a new motherboard Asus M5A99FX PRO R2.0 and found out
that IO speed is very low; i.e. the dd command output:
