    Subject[PATCH net-next RFC 0/5] batched tx processing in vhost_net
    Date
    Hi:

    This series tries to implement basic tx batched processing. This is
    done by prefetching descriptor indices and update used ring in a
    batch. This intends to speed up used ring updating and improve the
    cache utilization. Test shows about ~22% improvement in tx pss.

    Please review.

    Jason Wang (5):
    vhost: split out ring head fetching logic
    vhost: introduce helper to prefetch desc index
    vhost: introduce vhost_add_used_idx()
    vhost_net: rename VHOST_RX_BATCH to VHOST_NET_BATCH
    vhost_net: basic tx virtqueue batched processing
