[netperf-talk] netperf only tests sending, not receiving packets?

You are missing something :)

TCP_MAERTS which is the TCP_STREAM test with "STREAM" backwards will 
have the netperf side receiving data sent by the netserver side.

The ./configure --enable-burst compilation mode which adds a 
test-specific -b option to the TCP_RR test to have multiple transactions 
in flight, which will give the effect of a bidirectional transfer.

More details in the manual.

happy benchmarking,
