Yep, this is the case: the silly window avoidance means we update the
advertised window only when it increases by at least one MSS.

Having WND == MSS is generally not a good idea regarding throughput because
that raises problems both with the nagle and delayed ack algorithm. You should
at least make sure the nagle algorithm is turned off when having WND == MSS,
although you can then still have

Is it worth adding a check like other checks that are in lwip_init?

A special page on the wiki about configuring the many buffers in LWIP

Up to 1.3.0, it seems to have been working with WND == MSS. And although this
is not a good idea regarding performance, there are applications where it makes
sense, e.g. if your system is too slow to receive two segments in a

Hi
I’m using lwip 1.3.0 and updated to 1.3.1 and found problem with

I receive small blocks of data (30 bytes) every 500 ms and on each I

On version 1.3.0 the window size on tcp ack is 512 (what is my
