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?
