Abstract (in Japanese) (See Japanese page) 
(in English) Next generation network functions are expected to be deployed on highly advanced infrastrucures towards AI-based autonomous network management. Such a cloud-native applications are promising in terms of management, however, their performance of packet processing is significantly lower than that of the baremetal-based ones. Many studies have focused on eliminating packet copy between the host and the guest. While the zero-copying approaches provide noticeable performance gain, there are still substantial gap between them. In this paper, we focus on efficiency of cache memory (L1 cache) under vhost-user to fill the performance gap. We examined various cache-related factors and their combinations. The result shows that over 50 Mpps throughput can be achieved (the gap can be removed) by integrating several optimizations such as elimination of false sharing and extra buffer spaces.
