running high performance tcp 600mbs or more
Sounds like you have a 1000 mbit LAN?
Unfortunately we have only tested a Xilinx Zynq with a 100 mbs adapter.
Hopefully Hein will chip in with some throughput figures too.
On a 100 mbs LAN we saw a nett throughput of up to 10 MByte, which is about the maximum you can get. This test was done with FTP, transferring big files to or from a RAM-disk.
If you have any questions about porting +TCP to your 1 Gbps MAC, please post them here.
Also I have developed a ‘iperf’ server for FreeRTOS +TCP, in case you want to do performance testing.
I find that ‘iperf’ isn’t very interesting, and like Richard wrote, it is important to see the performance in real life.
figure out how to implement in raw mode
Within +TCP there is only one mode, which is the official BSD interface. But there are some back-doors, for those who prefer speed above compatibility:
- The use of zero-copy for sending and receiving, both for UDP and TCP.
- The use of call-backs from the IP-task such as OnReceive, OnSent, and OnError. These hooks are installable per socket.
An echo server which uses an OnReceive handler will have a higher performance because it uses less context switches and less copying.
