RTCS performance

[admin]

I have ported NETIO TCPIP server to measure network performance of RTCS. The test sends 1k, 2k, 4k, 8k, and 16k data blocks and measures the data thought based on the time around. The test was done for MFC52259 evb. Here are the results:

Packet size, Bytes   RX speed, Bytes/s     TX Speed Bytes/s
1024                          114688                           6627

2048                          139264                           22071

4096                          212992                          18542

8192                          305152                          19156

16384                        424960                          240640

It seems the transmission speed is really low. Do you have any similar test results showing different performance or this is the actual performance we have to expect?

The default build parameters for RTCS for the 52259 are set to optimize memory, not speed. There are a number of parameters that can be adjusted that will result in better throughput, at the expense of additional memory. If you want to provide your NETIO port, we may be able to suggest which parameters should change.

I have been using minimal RAM configuration which is default for MFC52259 and tried to change the socket options for buffer sizes (OPT_TBSIZE, OPT_RBSIZE) improve performance. Nothing worked. I have attached the port to the message.

Thanks. There are other parameters that will also affect performance. Will update you after looking at the code.
