iperf measurements #38

Closed mitar closed 9 years ago

mitar commented 9 years ago

I made iperf measurements between server2 and all APs on ethernet. On server2 I ran:

iperf -s

And then on each AP I ran:

iperf -c 10.20.32.10

Results:

Server listening on TCP port 5001
TCP window size: 85.3 KByte (default)

On APs TCP window size was 21.0 KByte (default).

It seems our network is nice 100 Mbit network. Some connections are more, but not really gigabit. :-) But I think it is good.
