My bandwith is slower out of the firewall lan ports, than it is on the wan side

I have 600Mbps coming into the USG60, but when measuring out from one of the USG's lan ports I only getting 250Mbps. Why is this?!

by TCP the most you might get is 350-400Mb as the 1000Mb listing for the USG60 is by UDP

Thanks you PeterUK! That did a lot with my speed. But still I am a bit disappointed that the 1000Mb is just for UDP. I did not know that before i bought this FW.
