Hi,

I got info from my customer;

We tried with teamproperlycompile and configure''LwIP_HTTP_Server_Socket_RTOS'' and STM32F4Cube onSTM32F407VG and DP838PHY.

Project was

successfullycompiled , but we noticed performance problems.

For tests we sended lot of pings from windowsmachineand results was not satisfied us

Response for ping took in average 500-600 ms.

In project we was using latestavailableSTM32F4Cube software.

Because of lack of performance we tried also use old NRND

Standard Library .

With same tests conditions we got satisfied us results - 1-2 ms for ping.

Code was completely rewritten basing onSTSW-STM32070

So my question is - where can be problem in

LwIP_HTTP_Server_Socket_RTOS and STM32F4Cube for performance problems? Can it be in connection with:

problems described:

Maybe is available workaround and/or better working www server or example basing on Cube?
