Forigate slowing the internet Speed

[Maan_Alhajjam]

Hi community,

I'm connecting a fiber connection to the firewall with speeds between 350 and 450 Mbps, but I'm only getting 10 Mbps in return. I understand that there will be some speed reduction, but is this normal???

I have disabled all security features in the firewall policy and the "threat-weight" configuration, but I am still experiencing the same speed issues.

Here is my configuration. Please, if you have any advice on how to increase my internet speed, I would appreciate it.

Hello Maan, 
Don't you have some traffic shaper applied to your policy ? 

And another point : 

If you have all time about 10 Mbps I suggest you to check any intermediary devices, as switch which can have only 100 / 100 Mbps. 

And please tell me, are you making tests from PC connected by wire or by WiFi ?

Hi Tajfun,

No, I don't have any shaper applied, and the speed is getting from a maximum of 17 Mbps to 8 Mbps.

I'm testing from the SSID I created in the Fortigate, and this is the configuration for it:

It looks like basic configuration. 
It the same problem if someone will try to access internet by wire ? 

And the simplest suggestion

Don't you have an antivirus/firewall on your computer that scans traffic and significantly affects its speed?
