What is your testing methodology? Is it iPerf? Trex? Something you can share so we might recreate and compare on our side?

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
