Re: [lwip-users] tcp echo example

[Sergio R. Caprile]

Hi,
when you say "echo example", do you mean the echo example in the contrib
tree or some vendor distributed (and probably modified) file ?
'cause i've run the echo example from the 1.4.1 contrib tree some weeks
ago and I don't recall seeing anything strange.
And btw, I don't see anything close to what you are describing in that
code, and there is only one tcp_write() call in echo.c:

address@hidden ~]$ grep -n tcp_write
programming/lwip/contrib/apps/tcpecho_raw/echo.c
311:  wr_err = tcp_write(tpcb, ptr->payload, ptr->len, 1);

BTW, if you want to really test the net throughput (or at least come
closer) get the netio patch: https://savannah.nongnu.org/patch/?7026

Regards
