摘要

网络速度的提高对网络系统的数据包处理性能提出了挑战。这主要归因于内核空间网络堆栈和用户空间应用程序之间的分离所造成的处理开销。为了减少这种开销，我们提出了Santa，一个与应用程序无关的内核级频繁请求缓存。通过允许用户空间应用程序将频繁的请求卸载到内核空间，Santa提供了巨大的性能改进，并为遗留服务器软件解锁了内核空间网络的速度，而无需进行大量更改。

Santa: Faster Packet Delivery for Commonly Wished Replies

Increasing network speeds challenge the packet processing performance of networked systems. This can mainly be attributed to processing overhead caused by the split between the kernel-space network stack and user-space applications. To mitigate this overhead, we propose Santa, an application agnostic kernel-level cache of frequent requests. By allowing user-space applications to offload frequent requests to the kernel-space, Santa offers drastic performance improvements and unlocks the speed of kernel-space networking for legacy server software without requiring extensive changes.
