@johnpoz:
Is this wifi or wired?
26MB is like watching paint dry for any sort of local copy.. So I take it this is wireless?
If anything your hairpin should be slower then when using 2 different nics.. But what other traffic is flowing at time of copy on these nics?
Yep, both situation is server on 1Gbps cable, client on 300Mbps wifi.
For cable to cable it will be better.
I can accept 26Mbps when on wifi, but 5 - 16Mbps is definitely too slow :o
I mean, for both conditions, gateway is involved, only difference is the first one is on same nic/port, second one involves two nic/ports.
But all of them are 1Gbps, and I don't see high CPU usage or high memory usage :-\ :-\
