Zynq 7000 Ethernet

Hello! The issue is related to the transfer of Ethernet packets to the MicroZed board. Transfer of short packets to the board, from 1 to 1458 bytes under TCP, acknowledge TCP is issued after 300 ms - this is a long, much longer, than on large packets - 60 microseconds. Used by Free RTOS, but under Standalone the same thing happens. It does not depend on the operating system. How to reduce the response time to the received user package of small length?

Re: Zynq 7000 Ethernet

Hi @hpetroff ,

Are you using LWIP and wireshark to send TCP packets and check the response time?

If so, you can try to tune LWIP performance with parameters , ie, check "configuring memory options" etc in lwip library documentation below:
