Hello, actually I'm coming from OpenStack. But we use the L2 Open vSwitch (1.11.0), so this is maybe the right place to ask.
The Hypervisor is KVM the Guest Windows 2012 R2 we use the latest virtio driver for the guest. We are facing some network performance issues on our webserver VMs. For example each DB connection or internal API query adds an additional latency by factor 2x. This accumulates and make the service latency wise to slow. We did some performance testing and the throughput from/to the VM is a little spikey. Especially the VM receiving from a bare metal (BM) machine seems to be significant slower. http://i.imgur.com/TByQsjZ.png Any tips to debug Open vSwitch regarding the latency or tuning tips? Thanks in advance! Greetings Chris
