Fortigate 50E not passing more than 223 MBPS on WAN port

You might want to check during the traffic test whether the FGT is on a high CPU load.

Also see what kind of traffic this is. If this is traffic decrypted at the FGT as a deep inspected VIP (SSL inspection = protect server) or an IPSec endpoint, this will cause considerable overhead.

You can test from the FGT directly with the traffictest command.

This one is described here:

Not sure how much UTM stuff or how many VPNs this 50E is handling. But I'm generally not comfortable putting a full Gig circuit on a 50E, which doesn't have any ASIC chips.

So the 50E is running at 16% CPU and is not handling any VPN traffic. All VPN traffic is forwarded to an internal OpenVPN server. 

This is from the provider showing bandwidth. This is a gig connect from them and we cannot get this to go any higher. I know for a fact that we are pushing 300 MBPS to this site.
