Subject: [Patch bpf-next v2 0/4] sockmap: some performance optimizations
Date: Mon, 2 May 2022 11:23:41 -0700 [thread overview]
Message-ID: <20220502182345.306970-1-xiyou.wangcong@gmail.com> (raw)
From: Cong Wang <cong.wang@bytedance.com>
This patchset contains two optimizations for sockmap. The first one
eliminates a skb_clone() and the second one eliminates a memset(). After
this patchset, the throughput of UDP transmission via sockmap gets
improved by 61%.
v2: clean up coding style for tcp_read_skb()
get rid of some redundant variables
add a comment for ->read_skb()
Cong Wang (4):
tcp: introduce tcp_read_skb()
net: introduce a new proto_ops ->read_skb()
skmsg: get rid of skb_clone()
skmsg: get rid of unncessary memset()
