VM Network speed low


My hypervisor nic speed is 100Gbps, While running an iperf test between 2 hypervisor i am getting 93Gbps/sec.

Deployed 1 VM’s are on each hypervisor. If i run a iperf test between those 2 VM’s i am seeing only 20.4 Gbps/sec its not going beyond 20.4 gbps/sec. I want to achive the same speed which i am getting on the hypervusor.

Hi @mac

Try to use virtio whenever possible, both for networks and disks. Using emulated hardware will have an impact on performance and will not expose all the available functionality.
