Hi all,

I’m doing iperf test on VIRTIO net through vhost-user(HW VDPA).

Find maximal acceptable tx_queue_size/rx_queue_size is 1024.

Basically increase queue size can get better RX rate for my case.

Can we increase the limit(VIRTQUEUE_MAX_SIZE) to 8192 to possibly gain better performance?

Thanks,

Yajun
