Our ISP provides us a fiber 500/500 connection.  When I connect my laptop directly to the ISP's Router I get the full 500Mbit/s Down and Up.   When connected to the MX via 2 switches (MX (Copper)<-> MS120-24 (Fiber)<-> MS120-24) I get around 180-250Mbit/s Down and ~300Mbit/s Up instead of the full 500/500 - or at least 400Mbit/s which seems to be the max. for the MX67.    In the traffic shaping rules, I have set the WAN 1 & 2 speed to each 700Mbps.  Primary Uplink is the ISPs Router.  There is no bandwidth limit enabled. The network uses no VPN.    I also tried disabling "Intrusion detection and prevention" aswell as "AMP".  Both had no impact on performance.   Currently running 18.210 Firmware.  Speedtest.net used for the tests.   Any ideas?    ...
