XL710's rate only reach 2.8Gbps

[Xiande]

I use XCZU19EG + XL710, XCZU19EG PS connect to XL710 by PCIE 2.0 x4, the firmware is XL710_X710_7p20_SFI_Backplane_MCTP_CFGID7p2_Quad.

when the Board came back,I tested it by iperf tool, and found that the rate can only reach 2.8Gbps. In my project, I only need one 10Gbps, so could anyone help me analysis the reason ? and how can I improve the rate ? Thank you .

Hi Amina,

Thanks for your reply.

About your concerned issues,

1.Exact product is FTXL710-AM2.

2.System is linux-5.15.

3.The adapter was pre-installed on the board, just like the picture shows in attchment.

4.Refer to the picture.

By the way, theFPGA XCZU19EG contains a A53 ARM core, the CPU frequency is only 1.2Gbps, I don't know if it matters or not.

Thanks!
