What does your quick and dirty test program use for socket buffer

netperf TCP_STREAM test of various socket buffer and send sizes?
For my test program I used a 8K send and receive buffers. The socket
buffers and options were left at default values.
8KB socket buffers, 8KB writes to the socket or both?
I tried netperf and the throughput numbers were virtually identical. I
could only use the default buffer sizes with netperf as the -[sSmMD]
options mentioned on the netperf website are missing.
Being test-specific commandline options they are placed after a "--" on
the command line to separate them from the global command line options:
netperf -t TCP_STREAM -H <remote> -- -s 128K -S 128K -m 32K
would be one example.
Also is there a way to do a reverse transfer with netperf without
switching to the other machine?
Yes, the TCP_MAERTS test (MAERTS == STREAM backwards)
