Hello Raymund,
I am using lwip 0.71, ported to a AT91RM9200 (160MHz ARM9, 100 MBit
<>Ethernet). It's doing constant "video streaming" with 9MByte/s via TCP.
I vamped a sampling profiler giving me this result:
...
<>As you can see the functions within the lwip library use the lesser
part of
cpu in this system.
You might roughly scale this to your target.
I use gcc 3.4.3 with -O2.
Excellent work, thanks for the analysis!
Regards,
Leon.
