Added to that, considering lwIP is working almost without lock (or just 
small one around memory allocation) and being totally non-blocking by 
the way it is designed should never be the reason of slowness over time.

DMA issues, interrupt issues, bus matrix overloading, etc, are in most 
cases the reason and obviously where to look first.
