Download speed limited to 10MBit on FortiGate 30E

[DirkS]

Hello,

After an upgrade of the internetspeed by the ISP from 100 to 200 Mbps up/down, multiple speedtests (Ookla, KPN glasfiber etc) show a download speed op 10MBit after the FG. Before the FG, the speed is correct.

There are no Traffic Shapers used except for 1 on VPN connections (2 Mbps). Also no load balancing settings are done..

The WAN interface shows a 1000 Full Duplex in it's configuration.

Firmware version is: v5.4.1,build1064 (GA)

Since I'm new to FG firewallls, can anyone point me in the right direction on how to solve this?

Thanks in advance!

Best regards,

Dirk

Hi,

I'm seeing the same thing on my Fortigate 50e device. It started to perform really poorly after a aprticular upgrade. I'm getting only about 20/20 mbps on a single session and maybe 30/30 on multiple sessipns if running iperf3 -P 10 for example. 

I'm womdering if Fortinet slows this on purpose?
