performance of LWIP + FreeRTOS

Question asked by dieter 123 on Feb 13, 2017


before I start my ethernet project, i would like to know the theoretical limits of ethrenet on STM32F407Z. What is the computational load on the ARM when running Freertos + LWIP + 100 mbs .

AN3102 only mentions SRAM/flash usage. 

How many percent of the 168 MIPS of the ARM will be consumed by LWIP and FreeRTOS when receiving UDP/TCP packets of payload length xyz? Is there a table with some numbers?
