limited upload speed fortigate 60e

I have a fortigate 60e with a free license, firmware v.7.2.3 build1262, which has a 4-port 802.3ad Aggregate trunk with a Cisco SF300-24 switch, a 200 Mbps symmetrical internet connection. This switch through the GE ports go to the LAN network. When I do an internet speed test, the measurement gives me a good download (230 Mbps) but the upload seems to have a limit of 100 Mbps because the speed measurement does not exceed 93 Mbps. I have done speed tests between the switches , between machines and they all give results of 1 Gbps within the internal network but the tests towards the internet give me the aforementioned speed of 220/93. I have checked the traffic shaping rules and everything is fine. Do you have any idea what could be happening? What do you suggest I check in the fortigate?

To isolate the issue, you can test the upload speed by connecting a device directly to the internet connection bypassing the FortiGate. This will help determine if the limitation is specific to the FortiGate configuration.se the CLI command "diagnose hardware deviceinfo nic <interface>" to check for any interface errors or issues that could be impacting the upload speed.

Yes, the direct test to the ISP is correct, it was the first thing that was validated. And internal network speed tests have been carried out and they have correctly given 1 Gbps. The problem is when accessing the internet through the firewall.
