Have you tried this for reference: VM1 -> system on extnet VM4 -> system on extnet Also, are you sure when packets from VM1 -> VM4 leave the vrouter1 interface they are still at the higher MTU? -Brian detected with iperf3 it's an openstack newton environment with openvswitch 2.6.1 VXLAN mtu is 8950 and 9000 for physical interfaces does anybody has an idea what could be the cause of the performance issue?

No, its a ha router (active/backup).

[openstack-dev] [neutron] performance issue between virtual networks
Hi, i've detected a performance issue by accessing an floating ip in a different openstack network (same tenant). example: i have one tenant with two internal networks. each network has its own vrouter which is connectet to the extnet. the physical network infrastructure is 10Gbit/s. networkA VM1 --| extnet ||vrouter1|| VM2 --| | |---ext networkB | VM3 --| | ||vrouter2|| VM4 --| VM1 -> VM2 ~8,6Gbit/s VM3 -> VM4 ~8,6GBit/s VM1 -> vrouter1 ~8.6GBit/s VM4 -> vrouter2 ~8,6GBit/s vrouter1 -> vrouter2 ~8,6Gbits VM1 -> VM4 ~2,5GBit/s VM1 -> vrouter2 ~2,5Gbit/s detected with iperf3 it's an openstack newton environment with openvswitch 2.6.1 VXLAN mtu is 8950 and 9000 for physical interfaces does anybody has an idea what could be the cause of the performance issue?
