Hardware Performance
It is difficult to differentiate the various network module vendors from the information in marketing and on web sites, especially in print type ads. This network speed test was created to enable you to see one of the most important aspects of network modules - speed in the form of network data payload throughput.
The network speed testing was done with the lowest cost NetBurner module versus the fastest available Rabbit module (which also happens to be a low cost module).
TCP speed test setup:
- Each device was connected through a switch to a test PC running Windows
- The identical PC and PC application was used for both NetBurner and Rabbit tests. Each test was run 50 times to average results. Results varied within +/-2%.
- The transmit test makes a TCP connection to the test PC, the PC starts a timer, commands the device to start sending 10MBytes of data, and stops the timer when all data has been received.
- The receive test makes a connection from the PC to the device, sends a command to the device to get ready to receive data, the device starts a timer, the PC sends 10MBytes of data, the device stops the timer when all data has been received.
- The "Parsing Test" simulates simple processing of the data by looking at each received character and determining if it is printable by a simple "if" statement:
if( (DataBuffer[] >= ' ') && (DataBuffer[i] < 128) )
PrintableChars++;
The results
These tests show that NetBurner is 20X (2,000%) faster at transmitting data, 7.5X (750%) faster at receiving data, and 50X (5,000%) better at receiving and parsing data.
We have included the source code on this web page so that you can try these tests out yourself. If you have any suggested benchmark tests that you would like to see, please let us know so that we can update these tests. Please E-Mail
