Hi,
I noticed weird behaviour of my Sophos XG firewall (Home Edition 17.1.1 MR-1, installed directly on PC with intel i5 CPU and 8GB ram). My internet speed from ISP is 100Mbps, I will only get 100Mbps speed after I reboot the Sophos, but after using it for few hours (roughly around 2-3 hours) the speed drops to around 15-17Mbps. I tested it few times using the reboot methods, the results are the same. All my tests are without enabling any UTM services, means allow any to any connections & disable IPS, Web policies, Traffic Shaping and Application Control also using direct cable connection from my laptop to Sophos LAN interface. Any idea what could cause the speed drops?
Remarks:
1) Tested using other small router, I'm getting consistent 98-100Mbps speed.
2) I am using Intel PRO/1000MT dual port server adapter as my network card.
3) Set interface speed to 1000Mbps - Full duplex (MTU 1500) on both WAN & LAN.
