[lwip-users] Latency with http_write

[Андрей Виноградов]

 

OMG, your idea to change TCP_TMR_INTERVAL solved my problem with http -)

 

I’m using stm32f2xx microcontroller as a small web-server. And see no problems with reducing TCP_TMR_INTERVAL down to 5 ms (didn’t tested 1 ms interval). No CPU loads. All smooth.

 

But I also changed TCP_SLOW_INTERVAL, made it 500 ms, because it depends on TCP_TMR_INTERVAL by default.

Also there is TCP_FAST_INTERVAL define, but it seems to be not used at all.
