RTCS performance

admin — Thu, 26 Feb 2009 06:25:18 GMT

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.
