Speed Tests

 Top  Previous  Next

These examples measure the performance for a particular system using the 3L Diamond TCP/IP stack:

•TCP_bandwidth_test_client_DSP
•TCP_bandwidth_test_client_PC
•TCP_bandwidth_test_server_DSP
•TCP_bandwidth_test_server_PC
•UDP_bandwidth_test_send_DSP
•UDP_bandwidth_test_send_PC
•UDP_bandwidth_test_recv_DSP
•UDP_bandwidth_test_recv_DSP

 

These examples generate traffic between PC and embedded processor and measure the average speed of the transfer.

Users can also use the Windows Task Manager\Networks to obtain more details about the transfers.

 

The transfer speed dependents on many factors and can vary from PC to PC, depending on the system load, datagram size (in UDP), size of buffers.

Please consider this and take the results of these tests as an approximation for a quick orientation.
