Do I need a 10G NIC in pfSense

Networking & Firewalls

Hi,

We have a pfSense at the head of our network in a datacenter that has all our xcp-ng host and VM.
In pfSense we have several network and vlan defined.
will having a standard 1GB NIC for the LAN (vlan are on lan interface) reduce the speed xcp-ng or the VM run at?

What would be the benefit of having a 10G NIC in pfSense?

Thank you

VM’s inside of XCP-NG lose almost no network speed being virtualized. So if you speed is 1gb or less, you don’t exactly need a 10G, but if more VM’s want to use the same NIC, the bandwidth is shared between those VM’s and might be a bottleneck.
