I don't any specific advice for your platform, but I do see that you are
using a very old (practically antique!) version of lwIP.

A lot of things in LwIP have improved since version v1.4.1 and very few
people use or have knowledge of such an old version these days.

It may be worthwhile to update to the latest release v2.1.1.

Also, make sure to use the latest STM32 drivers. I had to fight with lost RX packets about a year ago with the STM drivers - and lost RX ACKs packets might result in delayed TX packets for TCP connections...

Although I don't know if this is your issue or if what I saw is fixed by now.


Disclaimer: I am not a LwIP developer, I just am a developer for some
commercial products using the STM32F2xx and STM32F4xx..
