[dpdk-dev] [PATCH v3 3/3] lib/vhost: restrict pointer aliasing for packed vpmd

2020-07-09 Thread Joyce Kong
Restrict pointer aliasing to allow the compiler to vectorize loop more aggressively. With this patch, a 9.6% improvement is observed in throughput for the packed virtio-net PVP case, and a 2.8% improvement in throughput for the packed virtio-user PVP case. All performance data are measured on Thun
