X520-da2 with Zyxel-gpon-sfp // Speed Issue

[bkay86]

Hi, finally i was able to establish WAN with my X520-DA2, the Zyxel Modul in a pfsense box. So technically its works but....

the speed isnt quiet good as expected. i will get only ~800 Mbits on my 1G from "Deutsche Telekom FTTH". The Telekom ONT gives me 1070 Mbits Downstream (thanks telekom for overprovisioning) out of the box. So not even the 940 Ethernet Cap. Is this a problem with my X520 card? Can the X520 handle 2,5 Gbit with this SFP ONT? Unfortunately i cant see if the sfp is running in 2,5G or in 1G Mode.

any clue? experience?

Hi @bkay86
I have an similar issue with much worst speed results (20Mbps instead of 200Mbps) not sure if issue is still actual for you, but will be quite interested to know, if you performed any extra setting on the module itself (hal settings etc) or resolve that issue by any other means.
Thanks

Hi, didnt find a Solution für this. But it turned out that the CPU wasnt handle more then 750-800 MBits Filtered so this was the bottleneck. i switched to an i5 Prozessor in the meantime.
