BF-3 DMA extremely slow

Hi, my DMA performance in copying a file from BF-3 to the host is 10Gbits/sec, which seems extremely bad. I ran the doca_dma_copy app, has anyone seen a better or similar speed?

Thanks

Hi ,

Please open a support ticket to enterprisesupport@nvidia.com
Once you open the ticket , make sure to provide sysinfo-snapshot from the server and ib_write_bw / ib_read_bw test command line outputs with doca_dma_copy test results .

Thanks
