Hi sylvailn and bill:
Thank you for your advise .
Current, I can keep sending and reveiving speed stable by modify enthernet DMA
data chain from 5 to 3. As I said that DMA data buffer become unvailable if set
the value to 5.
But there is another problem, it maybe not performance issue . I am no

Hi:
I am working on LWIP1.4.0 and FreeRTOSv7.1.1 to setup web server with SOCKET
API..and found that sending speed becomes lower.
In order to know the actual sending speed, I write a simple application to test
it. And found that the sending speed is up to 8Mb/s. it is high enough for me.
I notic
All:
After set socket with attribute SO_RCVTIMEO, how does application know receive
timeout in this case? Is there a signal or call back to notice application ?

You use MTU SIZE as RX buffer, in ST code, it define RX buffer like uint8_t

So, you only set ETH_RXBUFNB to 1 ?

Hi:
I found a odd strange in Cortex M3, running LWIP1.4.0 + FreeRTOS.
I write a TCP server to accept large file, the code works well if running in
LWIP standalone. The performance is high and stable.
But when I create the task in FreeRTOS, the whole LWIP performance goes to down
after the task a

Hi :
I use latest LWIP1.4.x from git repo, and found that the problem of receive
speed down after sending file 3 times.
My code is pasted as following .
My system is FreeRTOS + lwip, I think it may be lwip bug
static void close_conn(struct tcp_pcb *pcb)
{
tcp_arg(pcb, NULL);
tcp_sen
pbuf_free(p);
}
if (err == ERR_OK && p == NULL) {
close_conn(pcb);
}
return ERR_OK;
}

Anyone know the problem ?
