The SpeedTest Sample

The SpeedTest Sample

The purpose of this sample is to measure the throughput capacity of the transmission channel as well as to benchmark the implementation efficiency.

SpeedTest is operated from the command line. It can be invoked using the following syntax:

SpeedTest server tcp|udp <port>
SpeedTest client tcp <hostname> <port> <numMessages> <messageSize>
SpeedTest client udp <hostname> <port> <numMessages> <messageSize> <reliable:true|false>

For example:

Start a server in UDP mode, listening in the port 2345.

SpeedTest server udp 2345

Connect as a client to a server running in UDP mode. Measure the performance by sending 100000 reliable messages of 450 bytes each.

SpeedTest client udp 192.168.0.100 2345 100000 450 true

When the test is run, the client begins to upload messages of the given size to the server until the count limit is reached.

The output should look similar to the following:

C:\Users\clb\Desktop\SpeedTest>SpeedTest client udp 192.168.0.100 2345 100000 450 true
Connected to 192.168.0.100:2345 (UDP, connected=true, maxSendSize=1400, sock: 192.168.0.22:61056, peer: 192.168.0.100:2345).
