Send throughput not actually testable

[stringhaml]

The windows version of ntttcp has the ability for a single sender to send to multiple receivers which does not work with this version of the utility. This served to essentially eliminate the receiver sides as bottlenecks allowing the client's send throughput to be fully measured. The windows syntax looked something like this: sender "ntttcp -s -t 60 -m 8,*,192.168.0.2 8,*,192.168.0.3 -l 256k -a 2 -p 5000"; receiver 1 "ntttcp -r -t 60 -m 8,*,192.168.0.2 -a 16 -p 5000"; receiver 2 "ntttcp -r -t 60 -m 8,*,192.168.0.3 -a 16 -p 5008".
