Linux guest slow network (KVM)


May 31, 2019
Using Linux virtio yields poor performance (~30MB/s capped) via lan/wan.

Using latest proxmox. It does not matter if it's gentoo or debian - 30MB/s max. sysctl changes appear to have no affect, including disabling offloading on guest/host.

INCLUDING host -> guest LAN.
Please post the output of pveversion -v, the VM config (qm config <vmid>) and which guest OS is running.
Have you tried E1000? How do you test the performance?
