Subject: [dpdk-dev] [PATCH 0/2] net/virtio: optimize virtio net header reset
Date: Wed, 11 Jan 2017 12:27:10 +0800 [thread overview]
Message-ID: <1484108832-19907-1-git-send-email-yuanhan.liu@linux.intel.com> (raw)
This two patches optimized the virtio net header reset when TSO is not
actually used (though it could be enabled). The basic idea is to not reset
(assign 0) when it's already 0. This could avoid some severe cache issues.
Micro benchmarking shows it could boost the performance up to 20+%.
