I've been pulling my hair out on this for the past hour and can't figure out what is wrong.
I shutdown my server earlier and moved it three feet away and reconnected everything the exact same way it was setup before. Now, for whatever reason, the maximum download and upload speed on the machine (and its jails) are capped at 1MB/s.
I have tried replacing the switch, numerous amount of cables, speed testing on computers on the same network, speed testing computers on the same switch, and restarted god knows how many times.
What can I do to locate the source of the issue?
Edit:
Forgot my machine details:
Lenovo TS140 Server (transplanted into a new case)
2x 16GB USB drives for boot
32gb ECC ram
5x 4TB HD's configured in a RaidZ2 configuration
I'm using the onboard NIC and had no problems reaching 150mbps (15 MB/s or so) for the past week.
As you can see the server was shutdown at 01:25 and booted back up at 01:45. No other device on this network is experiencing any speeds as low as my FreeNAS server is.
SOLVED: I fixed it. In case anyone else has similar issues, it relates to having an active AMT KVM session (using RealVNC) while the server is rebooting.
First I used:
This returned:
Then I checked my interfaces with:
This returned:
This made absolute no sense since the NIC obviously supports 1000baseT.
So I then tried forcing the media change:
There's that pesky 'SOL/IDER' thing again. After Google searching I found this thread:

Specifically this post:
It's interesting that this hasn't happened before, but as soon as I shut AMT KVM session off and ran "ifconfig em0 media auto" the em0 interface reconfigured from 10baseT to 1000baseT.
I hope this helps someone.
