Some results of speed test. It would be better to use a dedicated iperf server to test the speed but this time I used att speed test and fast.com. The router was connected (WAN) to pfsense , pfsense is connected to fiber / 1Gb line, the client (WIN10) was connected using LAN port of the router. All 3 devices run MWAN3 and some other services:
