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

Older laptops are not effected.
Ilya your post where my guiding stars! Thank you.
Also, I think issues like “Remote Desktop VNC very slow”
http://ubuntuforums.org/showthread.php?t=1752116&page=2
and many others could have been results of this bug and users not realising
that LAN speed is the issue..
Issue remains unresolved for me.
