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

    Hi,

    when on the same VLAN the traffic will not be hitting the XG, but managed by your switch.

    When on seperate VLAns then the traffic goes via the XG.

    Do you have memory and CPU locked in size and exclusive use of the XG?
