[ovs-discuss] OpenVSwitch latency issues

Hi 

It looks like it's the one which comes with OpenStack:

# modinfo openvswitch
filename:
/lib/modules/2.6.32-431.23.3.el6.x86_64/kernel/net/openvswitch/openvswitch.k

Linux 2.6.32 doesn't come with an openvswitch kernel module, so what version
of the kernel module do you have?  Some performance improvements will only
come with a sufficiently new kernel module.
