If an announced UDP throughput of 175 Mbps corresponds with an actual TCP throughput 80 of Mbps (45 %) then an announced throughput of 350 Mbps correspondingly should give 157 Mbps TCP and we still risk running a bit short with no with no room for upgrading the line :) Hmmm ...

The stated throughput is 175Mbit. There is a lot of room for improvement. And if this product under performs the whole product range might as well under perform. Or maybe it is possible to configure the product to perform as listed? Explaining it as 'low end unit' is a counterproductive simplification of the problem :) 

We are experiencing a low throughput on our Zywall USG 20W. We have a 170 Mbit connection but only obtain 80 Mbit thought the USG. We use latest 3.3 v. 9 firmware and have disabled ADP. When testing without the USG we get 170 Mbit. Disabling the firewall gives 100 Mbit i total. please advice.
