Disable traffic shaping policy on FG and test again.

Check for fragmentation. MTU size.

Check for duplex/speed mismatch - both sides of the fgt connection (e.g. lan side -> fgt < wan). 

 

e.g. From the CLI:  diag hardware deviceinfo nic <interface name>

 

You are looking for any error counters that increase over time.

 

Do keep in mind that depending on how the UTM features are applied to the traffic it will slow down the throughput somewhat.
