Subject: [PATCH net-next V2 0/3] rx busy polling support for virtio-net
Date: Wed, 16 Jul 2014 14:21:44 +0800 [thread overview]
Message-ID: <1405491707-22706-1-git-send-email-jasowang@redhat.com> (raw)
Hi all:
This series introduces the support for rx busy polling support. This
was useful for reduing the latency for a kvm guest. Patch 1-2
introduces helpers which is used for rx busy polling. Patch 3
implement the main function.
Test was done between a kvm guest and an external host. Two hosts were
connected through 40gb mlx4 cards. With both busy_poll and busy_read are
set to 50 in guest, 1 byte netperf tcp_rr shows 116% improvement:
transaction rate was increased from 9151.94 to 19787.37.
Changes from V1:
- split the patch info smaller ones
- add more details about test setup/configuration
Please review.
