Subject: [PATCH V2 0/2] vhost_net polling optimization
Date: Mon, 30 May 2016 02:47:52 -0400 [thread overview]
Message-ID: <1464590874-39539-1-git-send-email-jasowang@redhat.com> (raw)
Hi:
This series tries to optimize vhost_net polling at two points:
- Stop rx polling for reduicng the unnecessary wakeups during
handle_rx().
- Conditonally enable tx polling for reducing the unnecessary
traversing and spinlock touching.
Test shows about 17% improvement on rx pps.
Please review
Changes from V1:
- use vhost_net_disable_vq()/vhost_net_enable_vq() instead of open
coding.
- Add a new patch for conditionally enable tx polling.
Jason Wang (2):
vhost_net: stop polling socket during rx processing
vhost_net: conditionally enable tx polling
