Wireless Performance Stats

I cannot get this thing to connect with Encryption On using the SMC software, so I cannot turn on/off this 'Nitro' thing...

http://www.stanford.edu/~preese/netspeed/ was used to test. This program ROCKS!!! Server Linux, client WinXP Pro. 30 seconds per test, 8KB window (default) You can see there is a push and a pull test.

Server:
iperf --format K --port 999 -s
Client:
iperf -c neuvreidaghey -r -t 30 -p 999 --format K

802.11g, with encryption on.

802.11g, with encryption off.

So I am getting 15-21 Mbps of 54 theoretical - THAT SUCKS!!! [27-38% efficiency]

802.11b, encryption off.

So that is 3.3-3.7Mbps of 11 theoretical - guess that G ain't so bad - it IS about 5x faster! [30-34%]

Just for shits, I switched the G router into B/G mixed mode environment... 802.11g (with b compat) [no encryption] [results about same as G only] I tried putting both NICs in the laptop at once, and things just got ugly. Guess with only one laptop I cannot get the B to interfere enough with the G... I will try that NITRO stuff again... maybe tomorrow, maybe this weekend.
