Hercules RM57Lx lwip performance

What is the max throughput that can be achieved on the TCP with the lwip stack ?  The two R5 cores is not required to run in lock step.

    Sreekumar,

    As far as I know this isn't something we've measured and the lwIP stack example we have is only demo-ware.
    You would need to measure it yourself. I can tell you that the choice of memory for your packet buffers will impact throughput just based on how the silicon works. [for example, placing the pbuf in slow async SRAM will cause problems if you are trying to sustain 100Mbps etherent throughput].

    BTW the RM57L is a lockstep device (L) and the cores only operate in lockstep. They cannot unlock.
