Hi. I used iper3 for testing. It happened only with geneve and vxlan. I can get full bandwidth with vlan. My env: Openstack 2025.1 Kolla Ansible master-2025.1 Ubuntu 24.04 with uplink 25gbps x 2 for bonding, lacp 802.3ad, layer3+4 Noticed: I used distributed floating IP for my system. I tried without distributed floating IP and got the same result. Nguyen Huu Khoi On Mon, Apr 28, 2025 at 11:15 PM James Denton <james.denton@rackspace.com> wrote:
What is your testing methodology? Is it iPerf? Trex? Something you can share so we might recreate and compare on our side?

Hello.
I am going with ovn for my system but when I use vxlan and geneve, my instance cannot get full bandwidth(12 gbps)-instance to instance with private network. It is ok if I use vlan or floating ip for instances.
My env:
Openstack 2025.1
Kolla Ansible master-2025.1
Ubuntu 22.04 with uplink 25gbps x 2 for bonding, lacp 802.3ad, layer3+4
Ps give me some points.
Thank
