Hi Team,
I am using virtio-net, virtio-pci drivers for a Bittware hardware. I
could see the data is sent and received with the throughput of 100Gbps.
But the hardware supports for 200Gbps. I am not able to get the
throughput more than 200Gbps.
I am using latest DPDK source files and I tested TestPMD application to
transfer and receive packets. I have noticed the virtio_ethdev.c
supports 200G, but while testing TX and RX shows 100Gbps.
I have increase CPU cores to more than 6 for each TX and RX. Still the
throughput remains in 100Gbps.
Could you please let me know what changes to be made and what debug area
I should look into.?
Thanks and regards,
Ayshathul Thuhara
