spirit replied to the thread Network Optimization for High-Volume UDP Traffic in PVE.this is normal, don't use vmxnet3 or e1000, they are full software emulation. you need to use virtio which use vhost-net offloading on pvehost. your cpu is quite old, and it's possible that spectre/meltdown/.... mitigation impact performance... -
spirit replied to the thread Network Optimization for High-Volume UDP Traffic in PVE.250566pps is quite low, I mean , you should reach 1~2mpps for any each packetsize. I remember to reach easily 7~9gbit with 1core/thread with standard 1500mtu. (with epyc v3 3,5ghz and cpu forced to max frequency)

spirit replied to the thread Network Optimization for High-Volume UDP Traffic in PVE.as far I remember, virtio-net is limit is around 2millions pps by core (depend of the cpu frequency). The only way is to increase number of queue on the virtio nic. (if you are cpu limited, you should see a vhost-net process at 100% on the pve...
