XG-7100 1U WAN throughput
-
Hi folks,
wrestling through some WAN throughput issues with my initial setup of a XG 7100 1U.
Setup 1:
PC direct connected to internet provider modem. Bandwidth test with internet providers server = ~900Mbps
Setup 2:
modem -> XG-7100 -> PC
I'm using Eth1 with the default WAN setup connected to the modem
and one of the LAN ports for the PC.Repeat the throughput test, and i get a burst to about 800Mbps, then decays immediatly to 200Mbps.
between two PCs on the LAN, i get ~900Mbps. It looks like whenever routing is encoutered my throughput can't maintain more than ~200Mbps.
All cable runs are < 50ft CAT 6.
What i've tried:
- using the PCIe riser + a Intel NIC 1Gbps as the WAN port (no change)
- SFP+ to RJ45 1Gbps in ix0 to the modem (worse throughput)
- replaced all cat6 cabling
This looks like a queueing problem that is CPU bound, but I don't know for sure
-
tried a factory reset, used the wizard to setup. WAN connected to modem, and just one PC connected to LAN.
Same results: peaked at about 800Mbps, finished with average of 277.6Mbps

That level of throttling is almost always something low level like a speed/duplex mismatch or an IP address conflict.
Check Status > Interfaces for errors/collisions especially when using the expansion card.
Check the system logs for any errors shown.
