Here are the results of KVM and LXC based virtual machines on Ubuntu 14.04.. Both look a fair bit better than the results you're seeing. --- LXC ping from VM host --- 10 packets transmitted, 10 received, 0% packet loss, time 9000ms rtt min/avg/max/mdev = 0.042/0.050/0.074/0.009 ms --- LXC ping from elsewhere on network --- 10 packets transmitted, 10 received, 0% packet loss, time 8998ms rtt min/avg/max/mdev = 0.167/0.217/0.326/0.048 ms --- KVM ping from VM host --- 10 packets transmitted, 10 received, 0% packet loss, time 9002ms rtt min/avg/max/mdev = 0.188/0.306/0.402/0.057 ms --- KVM ping from elsewhere on network --- 10 packets transmitted, 10 received, 0% packet loss, time 9000ms rtt min/avg/max/mdev = 0.263/0.370/0.459/0.067 ms On 5 February 2015 at 12:27, Peter Ross <Petros.Listig@fdrive.com.au> wrote:
Hi,
the SAGE consultant was noticing the network latency on the "internal switch". He did not like VirtualBox + FreeBSD for that matter (I don't blame him - it was the first "get something up" quickly" configuration).
Here the values:
--- SageApp.vv.fda ping statistics --- 10 packets transmitted, 10 packets received, 0.0% packet loss round-trip min/avg/max/stddev = 0.308/0.635/1.364/0.319 ms
It did not change much when moving to another network card (following David Lutz' recommendation: https://dlutzy.wordpress.com/2012/04/23/performance-problem-with-virtualbox/ )
However, there is a Windows box on the Oracle VM Server running, and here I have:
--- SageWindows.vv.fda ping statistics --- 10 packets transmitted, 10 received, 0% packet loss, time 9002ms rtt min/avg/max/mdev = 0.554/0.605/0.646/0.037 ms
So the average is not much different but the variance higher.
However, he says, he sees typical 0.15 ms values on his PC with VMware Workstation.
I wonder whether someone can share thoughts and experience about it (and other performance values).
I found this interesting too:

I will take some time to play with various setups in the near future.
