SFOS 18.0.0 GA-Build354 Extremely slow throughput - XG Home - Physical Box

Hi,

I am running Sophos Home XG on a Shuttle PC with 2X GbE port (Intel i211) NIC's on the board.

I am experiencing extremely bad throughput.

I am in Australia - NBN FTTP connected via PPPoE with Internode.

So, running 17.5 MR10, no issue whatsoever.

Now SFOS 18.0.0 GA-Build354 it is terrible.

I have:

• Messed with the Port 2 MTU - Originally set at 1500, I seem to be getting the best speed with 1425
• Opened the Firewall rule and disabled:
  • Block QUIC
  • Apply Web Based Traffic Shaping (wasn't on anyway)
  • Scan HTTP and decrypted HTTPS
  • Scan FTP for malware
  • Use web proxy instead of DPI engine (wasn't checked)
  • Decrypt HTTPS during web proxy filtering
• No IPS set

Here is a screenshot with these settings

Now, if I go to my NTD and plug my device directly in and setup a PPPoE connection here is what I get:

I have rebooted, hard coded speeds on the Port 2 port (100mb Full) as with V18, auto detect fails and hard coding 1000mb also fails - Thanks rfcat_vk for helping with that at this post
