Hello,
Beside the Sophos firmware drama I do have a pretty mysterious performance (1.20 Mbits/sec) issue with one of my Red 50 since a about MArch 2020.
The story started with the Sophos firmware action, So I received a new Red 50 /RMA/ and since this Red switch I do have a very slow performance especially on the Upload side but also with Download...So I started to double check all 4 internet uplinks (utm and red site) which are good and I also checked all cables on both sites IPS, etc. without success. So I contacted Sophos and my Local Reseller and I received without any real special investigation a new Red50 /RMA/ cool but with now my 3'd Red in 2020 my super bad performance persists ;-(
I tried a lot (mtu change) different endpoints for my red, balancing and failover, compression on and off, disable IPS and the firewall for the Red networks, split and unified usw.
I do reached a point whitout any further ideas, If someone has an idea, PLEASE LTME KNOW!
