This explains why I can't improve performance just adjusting TCP_WND.  
Since I'm trying to optimize for throughput rather than  latency, I'm 
minimizing the number of pbuf's in the pool and maximizing the each 
one's memory space. From your words, I see that I should review this 
strategy and take TCP_WND into account.


Thanks for the help
