[PATCH V2 0/2] vhost_net polling optimization
From: Jason Wang
Date: Mon May 30 2016 - 02:48:03 EST
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
