tcpblaster Performance Test Example
===================================

To set up, do `make menuconfig` and select the Apps > Examples > tcpblaster. By default, nuttx will the be the client
which sends data; and the host computer (Linux, macOS, or Windows) will be the server.

Set up networking so the nuttx computer can ping the host, and the host can ping nuttx. Now you are ready to run the
test.

On host:

    $ ./tcpserver
    Binding to IPv4 Address: 00000000
    server: Accepting connections on port 5471

On nuttx:

    nsh> tcpclient
    Connecting to IPv4 Address: 0100000a
    client: Connected
    [2014-07-31 00:16:15.000] 0: Sent 200 4096-byte buffers:    800.0 KB (avg   4.0 KB) in   0.18 seconds ( 4444.4 KB/second)

Now on the host you should see something like:

    $ ./tcpserver
    Binding to IPv4 Address: 00000000
    server: Accepting connections on port 5471
    server: Connection accepted -- receiving
    [2020-02-22 16:17:07.000] 0: Received 200 buffers:   502.9 KB (buffer average size:   2.5 KB) in   0.12 seconds ( 4194.8 KB/second)
    [2020-02-22 16:17:07.000] 1: Received 200 buffers:   393.1 KB (buffer average size:   2.0 KB) in   0.09 seconds ( 4299.4 KB/second)


This will tell you the link speed in KB/sec – kilobytes per second. If you want kilobits, multiply by 8.

You can use the `make menuconfig` to reverse the setup, and have nuttx be the server, and the host be the client. If you
do that, start the server first (nuttx), then start the client (host).
