Problem with speed SDWAN ISP

[Adler]

Hello I have fortigate 30E with firmware v6 2 13 build1343 GA SD WAN with 2 ISPs is configured on the device Recently I noticed a problem with the connection speed on both interfaces. 100/100 link speed shows 5-10 Mb. I don't have any traffic shapers configured. When I connect the computer directly to the ISP, the problem does not occur. Please help.

Is this a new issue? Did it ever work well on the FGT-30E?

Do you have security profiles applied to your firewall policy?

The problem appeared a week ago. Where can I check it?

so all was fine and you were getting full speed up until a week ago?

something must have changed. any config changes on the fw? firmware upgrades? any changes to the internal network?
