时间很重要。在整个系统延迟中，延迟不仅仅是对用户的滋扰，而是在高频交易等领域中降低了应用程序的延迟。在许多数据中心中，延迟很容易转化为迄今为止的研究。为了使用一组精心设计的实验，我们探索了许多延迟的终端延迟到电线。应该向主机内的延迟付款，并表明没有银弹来解决数据中心的端到端潜伏期挑战。集中研究，提高用户的经验质量。
Time matters. In a networked world, we would like mobile devices to provide a crisp user experience and applications to instantaneously return results. Unfortunately, application performance does not depend solely on processing time, but also on a number of different components that are commonly counted in the overall system latency. Latency is more than just a nuisance to the user, poorly accounted-for, it degrades application performance. In fields such as high frequency trading, as well as in many data centers, latency translates easily to financial losses. Research to date has focused on specific contributions to latency: from improving latency within the network to latency control on the application level. This paper takes an holistic approach to latency, and aims to provide a break-down of end-to-end latency from the application level to the wire. Using a set of crafted experiments, we explore the many contributors to latency. We assert that more attention should be paid to the latency within the host, and show that there is no silver bullet to solve the end-to-end latency challenge in data centers. We believe that a better understanding of the key elements influencing data center latency can trigger a more focused research, improving the user’s quality of experience.
