Hello. Yesterday we migrated our Proxmox VPN server from QEMU virtualization to an LXC container, and when we connected to the VPN and measured the speed on speedtest.net, the download speed was 0.98 Mbps, less than 1 Mbps. Upload speeds were about 30 Mbps, which was typical. When running with QEMU virtualization before, vmxnet3 was used as the paravirtualized network device. This is because vmxnet3 is the best performing of the standard installed devices.

Since there is no option to select a paravirtualized network device model in the LXC container, I am not sure how to improve the performance of the VPN connection. if anyone knows how to improve the performance of the network device in the LXC container, please let me know. If anyone knows how to improve the performance of the network devices in the LXC container, we would appreciate it.
