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 <[email protected]> wrote: > Hi, > > the SAGE consultant was noticing the network latency on the "internal > switch".
