I have a new Sophos XG115 without any firewall rule besides the default one, with a basic license, default webfilters and no IPS activated. It is connected to a router and to a internal switch. Both interfaces have 1000 Mbps - Full Duplex Auto-negotiated. When I make a speed test I'm at around 30 Mbps Up and Down. But when I try to open a website, it takes 15 seconds or more. Before we set up the firewall it was much faster. Also over the old WLAN, who is not behind the firewall it is much faster as well.
Any idea what could cause that?
I checked everything for udpates. But unfortunately this didn't solve anything. I also tried to deactivate the AV and IPS Service but that didnt help too.
on the second screen shot, you have only shown the top part of the page, there are more settings below that might be having an effect.
Hi,I booted to the firmwarew SFOS 16.05.3 MR-3 which came preinstalled and here the performance is fine. So it seems there is a bug or something in the new version.
