Atheros GbE LAN chip max speed

Solution
GBE is gigabit ethernet so theoretical limit is 1000 Mbps and what you should get is ~950-890 Mbps (~120 MB/s).
you can test that easly with iperf. I'm inserting example output with replaced ip's with names (wifi):

------------------------------------------------------------
Client connecting to "laptop", TCP port 5001
TCP window size: 45.0 KByte (default)
------------------------------------------------------------
[ 3] local "laptop" port 59560 connected with "desktop" port 5001
[ ID] Interval Transfer Bandwidth
[ 3] 0.0-10.0 sec 200 MBytes 168 Mbits/sec
