hi,
When I used xdma ip to transfer data, 128KB data-size on h2c almost reached full speed. But 32KB data-size on c2h, the speed decreased significantly sometimes. Just like the 3rd transmission on the picture below, when I debug axi_bram_controller.
How can I get full speed like h2c?
PS My project worked on VU9P and PCIE Gen 3.0 x16. The host CPU is intel I9, OS is ubuntu
