Jason Wang 4afb52c2af vhost_net: batch update used ring for datacopy TX ... Like commit e2b3b35eb9 ("vhost_net: batch used ring update in rx"), this patches implements batch used ring update for datacopy TX (zerocopy has already done some kind of batching). Testpmd transmission from guest to host (XDP_DROP on tap) shows 25.8% improvement (from ~3.1Mpps to ~3.9Mpps) on Broadwell i7-5600U CPU @ 2.60GHz machine. Netperf TCP tests does not show obvious differences. Signed-off-by: Jason Wang <jasowang@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>		2018-07-22 09:43:31 -07:00
