Thanks.  If I have interpreted your answer correctly what you call 
TCP_STREAM RX should be the same as TCP_MAERTS TX and vice versa 
(modulo having the same -s, -S, -m and -M values or system defaults 
anyway)  Ie

system-A> netperf -H system-B -t TCP_MAERTS ...

should be the same as

system-A> ssh system-B netperf -H system-A -t TCP_STREAM

I put the TCP_MAERTS test into netperf specifically to help people avoid 
having to ssh :)

happy benchmarking,

PS, if I or anyone else ever gets around to implementing the sendfile 
functionality in the "omni" tests, then they should also provide what we 
might call a TCP_ELIFDNES test - the netserver side calling sendfile() 
to send data to the netperf side.
