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 accept file for a while
It seems that switch task in FreeRTOS cause it down, but I don't know how to bypass. I even try to "define LWIP_TCP_CORE_LOCKING' To disable TCP task switch, but still got same result . Anyone can give help ? vincent
