[..] I am able to reproduce the same problem using curl on windows and

takes about a second! If I do the same request with python it takes
some milliseconds. Why? I guess the problem is not directly related to
lwip but I do not have any clue where the problem is located. I put
the wireshark output below. First is the output of the curl request,
second the same request using python. Any ideas ?
Yes: send a pcap, not some text. From the text output you sent, it
seems obvious that the 1st version delays packets. Without having a
look at the packet details, it's hard to tell why.
