Can't reach full 10Gb when crossing VLAN ?

Nabil R1

Hi all,

I'm using Sophos XG Home with dual SFP+ ports that can theoretically reach 10Gb. I have 3 machines with these.

If I perform iPerf3 from Machine X to Machine Y, I get the full 10G when they are on the same VLAN.

If they are not, then the speed drops quite a bit (2.5 Gb ish, sometimes 1Gb).

IPS/DOS are turned off, and when I look at the performance graph, it doesn't look like the CPU is maxed out.

Note, Sophos is running on a VM in Proxmox.

Thanks
