HI all,

      I used the TCP server model to test the network speed. The Z0 core can reach 30mbps, and the Z2 core can reach 20Mbps. Can it be higher? I hope it can reach 50Mbps.   development environment:S32 Design Studio,mpc5748G,sdk RTM 2.0,lwip with baremetal .

Best Regards,

Hi,

I got information that benchmark test was done on LWIP demo which is available in SDK. Iperf version 2.x (client) from website iperf.fr was used.

This command was used: iperf.exe -c 192.168.0.200

... where 192.168.0.200 is address of board.

Here is the result:

Also notice that RTM 3.0.0 is already available.
