Sonicwall TZ400 throughput

Hi All,

I'm seeing an issues with some of our Sonicwall TZ400's. Based on the spec sheet they should have no troubles with throughput off 100+mpbs with security features turned on but we're lucky to get 50mbps out of a 200mbps circuit. I've disabled every security feature, turned off DPI and verified all interfaces are 1000/full. Testing from the modem I get 240, soon as I plug the firewall in and go behind it I'm around 50 max. We have other locations that seem to get 100mbps with no problem, running an identical firewall config with security services turned on.

Anyone have experience with Sonicwalls?
