What sort of command lines were used for each test?

By default, netperf passes what could be very compressible buffers to 
the stack - dies 802.11b try to do any compression?

BY default netperf accepts the system's default socket buffer and thus 
window size.  Does iperf do that, or have its own default?

soooo many possibilities, we need to know more about your tests to take 
more accurate guesses.

happy benchmarking,
