I have a problem in a production environment where I have one small server running as a guest on a hyper-v 2012 host. All this machine does is run a small <100 line node.js http proxy. I have tested the system on a variety of other configurations, even my travelling laptop running 14.04 desktop and everything else I have going on and it works without trouble.
The network performance of this guest server is terrible, almost unusable. The only clue I have to what is going on is that ifconfig reports really large numbers, around 30%, of dropped receive packets. This is on an internal network, it isn't public facing at all. Dmesg and syslog are all quiet on the networking front.
Outputs from uname -a, uptime and ifconfig.
I would really appreciate some advice as to how to diagnose or solve this problem. I have pushed for this solution with a welded on microsoft loving client, now I am starting to look bad....
I have of course asked many globally recognised search engines, but no solution seems to be available. I should also mention that this machine is a three hour drive away, I do however have ssh access. I am reluctant to fiddle too much with the networking settings without good reason in case I hose the interface.
Thanks in advance.
