XG cuts bandwidth to the half

Question

Hi all, i have the issue, that when I use my xg the internet bandwidth cuts to the half. I have a 200 Mbit connection and when i am using the XG i only get ~ 90 Download / 10 upload When i am directly connected to the provider router i get 190 Mbit, so i think the connection is ok . 
 
 Settings: 
 - XG 115w - interface is connected via 1000 Mbps - Full Duplex - firewall rule on top with no ips , qos , web or application - System Services -&gt ; Traffic Shapping Settings is set to 200 000 Did i forget any options? 
 
 I am thankful for every tip! 
 Regards, Max

Hi KL, 
 Parameters XG125 (below) indicate that 800 Mbps is unattainable. In my experience for XG125 rev.2 with protection functions enabled it is max 450 Mbps. XG125 rev.3 should be a bit faster. The heavy load causes IPS. It should be noted that IPS works even when it is not used in rules. You can disable the IPS service but is this a good solution? 
 rev.2 
 
 rev.3

Hi KL, 
 Currently only XG125 / 135 rev.3 are sold. To make full use of the 800 Mbps band, XG135 rev.3 would be needed (XG125 has weaker parameters, especially AV proxy). For the 1.6 Gbps band, an even more powerful XG210 would be needed. You need to consider the profitability of the investment.

Hi Garuda , 
 Then you may need to adjust the value of 
 MTU to 1492 and MSS value 1452. 
 MTU to 1500 or 1492 and MSS value to 1412. 
 You may adjust the range of MSS between 500 to 1460.
