Hi all,
I have a question on lwip ACK delay.
Echo sever is used
lwIP <-------------------------> PC WINDOWS
--------------Send------>
<- - -windos ACK
<------Echo back------
- -lwIP -tcp ACK - - - >
I send 2047 data, (mtu is 1024).
driver send 1024 firsst
1024 send
In wireshark, I could see the ACK delay.
if small data, 123 byte, lwip ACK send about 7xx ms
if 1024 data, lwIP ACK is about 1s
so 2048 data will be get after 2s.
>>How could I change the default ACK delay?
I tried to let lwIP ACK remote as quick as possible.
Thanks
