What speeds are you getting via local interfaces?

You may have some NIC’s that are incompatible. The XCP-NG forums might be more helpful for that https://xcp-ng.org/forum/category/3/network

If the VMs are Windows guests then you’ll definitely want to load drivers (think Xen calls it XenTools? if I’m not mistaken). Otherwise it’s likely using older, more compatible NIC/disk emulation which results in horrible performance.

I primarily use Proxmox and any Windows VMs need virtio drivers setup at install to perform well.
