Hi -

 From time to time I web search for instances of netperf usage, and came 
across http://www.spinics.net/lists/linux-wireless/msg76387.html  which 
has verbiage like:

in it. Seeing separate TX and RX lines for netperf TCP tests is 
unfamiliar to me and I was wondering if someone (Stephan?) could explain 
the split?  Netperf itself tends to emit only the one figure for a 
transfer rate (measured up at the socket level). (Modulo some of the 
recentish omni output selectors anyway, though for a TCP transfer test 
they would/should be very very similar...)

thanks, and happy benchmarking,
