Hi all: This is an RFC to try to speed up TX by avoid cleaning transmitted packets in start_xmit() when TX NAPI mode is enabled. This increase 25%-62% PPS depending on the setups while keeping the TCP throughput.
More numbers could be seen in patch 2. Thanks Jason Wang (2): virtio-net: factor out logic for stopping TX virtio-net: free old xmit skbs only in NAPI drivers/net/virtio_net.c | 53 ++++++++++++++++++++++++++++++---------- 1 file changed, 40 insertions(+), 13 deletions(-) -- 2.34.1
