FreeTCPIP doubt

Hi , I am using FreeRTOS demo project as a base for one of my project. I found that TCP/IP stack used in this project is modified uIP stack. I am having modbus application over TCP/IP stack, Will FreeTCPIP satisfy my througput requirement? Will FreeTCPIP be developed in future? one more question: Can i shift to uIP at any point of time in this project without much effort?

FreeTCPIP doubt

The code you refer to is extremely old and only kept in the download for backward compatibility with old demos. There will definitely not be any further development on it as we now have our own TCP/IP stack http://www.freertos.org/tcp
Will FreeTCPIP satisfy my througput requirement?
That will, of course, depend on your throughput requirements, which at this point only you know.
