Subject: [dpdk-dev] [PATCH v2 0/5] virtio: Tx performance improvements
Date: Sun, 18 Oct 2015 22:16:07 -0700 [thread overview]
Message-ID: <1445231772-17467-1-git-send-email-stephen@networkplumber.org> (raw)
This is a tested version of the virtio Tx performance improvements
that I posted earlier on the list, and described at the DPDK Userspace
meeting in Dublin. Together they get a 25% performance improvement for
both small packet and large multi-segment packet case when testing
from DPDK guest application to Linux KVM host.
Stephen Hemminger (5):
virtio: clean up space checks on xmit
virtio: don't use unlikely for normal tx stuff
virtio: use indirect ring elements
virtio: use any layout on transmit
virtio: optimize transmit enqueue
