Maybe the ones using netconn or socket API don't have any problems? :-)

But really, I haven't used the netconn API so far, but the socket API solves 
many lwIP-related difficulties for the programmer and thus makes programming 
applications easier. But of course there is a performance-gain using the raw 
API. Depending on the system you are using, the frequent task changes (between 
tcpip_thread and application thread) can be *very* time-consuming. However, 
using the netconn API, the task changes should be the only performance drawback 
against the raw API.
