Iperf testing, same subnet, inconsistent speeds.
-
@erasedhammer said in Iperf testing, same subnet, inconsistent speeds.:
I have to research if dismantling bond0 to get two separate nics on Synology would break connectivity permanently
Yeah, probably don't do that!
-
Deleting the bond0 has left one interface intact with the correct IP address. So I was able to use the secondary interface to test speeds directly.
It seems pretty clear that pfsense is not the problem at all.
Getting the same speeds directly with a laptop directly connected to the NAS.
Iperf3 test shows network is not the problem.
