This page provides details related to the light weight IP (LWIP) library and the SW app lwip echo server.

...

The following features are not supported but in plan:
MCDMA
10G/25G MAC

Performance

...

Performance measurement with lwip library can be done using the TCP/UDP server/client SW apps:
Raw mode:
https://github.com/Xilinx/embeddedsw/tree/master/lib/sw_apps/lwip_tcp_perf_server
https://github.com/Xilinx/embeddedsw/tree/master/lib/sw_apps/lwip_tcp_perf_client
https://github.com/Xilinx/embeddedsw/tree/master/lib/sw_apps/lwip_udp_perf_server
https://github.com/Xilinx/embeddedsw/tree/master/lib/sw_apps/lwip_udp_perf_client
Socket mode:
https://github.com/Xilinx/embeddedsw/tree/master/lib/sw_apps/freertos_lwip_tcp_perf_server
https://github.com/Xilinx/embeddedsw/tree/master/lib/sw_apps/freertos_lwip_tcp_perf_client
https://github.com/Xilinx/embeddedsw/tree/master/lib/sw_apps/freertos_lwip_udp_perf_server
https://github.com/Xilinx/embeddedsw/tree/master/lib/sw_apps/freertos_lwip_udp_perf_client

Xilinx HW running one of the above lwip applications can be connected to a standard linux machine (Ubuntu) to obtain optimal performance numbers.
Raw or socket mode TCP/UDP client/server can be run on Xilinx HW while the iperf server/client (in suitable pairs) can be run on the linux machine.
Refer to the SW apps' README files for more information

NOTE: These performance tests are not supported or benchmarked with emaclite. The application throws an error message to indicate the same when built on emaclite designs.
