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).
