| Abstract(in English) | Cloud Native Network Functions (CNFs) have been adopted in cutting-edge commercial networks for flexible and agile operations; however, the throughput of them is reduced by about 40% at maximum compared to that of bare-metal environment. Our previous study revealed that CPU cache pollution in virtual network I/O (vhost-user) was the major performance bottleneck. To further improve the performance, explicit control of CPU cache usage is a primary goal because well-known optimization techniques, such as cache-line alignment and prefetching, have already been fully introduced in the implementation of vhost-user. While some approaches of explicitly controlling CPU caches were effective for network functions in a bare-metal environment, no such approach has been proposed for CNFs (i.e. virtual network I/O is not considered). In this paper, we analyze the CPU cache usage in virtual network I/O (host-guest direction) and examine Non-temporal instructions for improving the cache usage. |
