Be careful with the newest virtio drivers (0.1.285), they seem to have some issues, maybe use older (0.1.271) ones for now.

depending on your actual processor you should set it to x86-64-v3 or x86-64-v4.
it exposes more processorflags/features to the OS.

im usually running them with v3, as my processors dont support AVX512.

the xeon gold 5118 supports AVX-512, so you could go with v4.
dont forget to set the +aes flag.

Thank you for the additional information. I am running it with v4 now and it doubled the rates again. Now I have finally reached the hardware limits and learned on the way. Thank You!
