Interactive services often have large-scale parallel implementations. To deliver fast responses, the median and tail latencies of a service's components must be low. In this paper, we explore the hardware, OS, and application-level sources of poor tail latency in high throughput servers executing on multi-core machines. We model these network services as a queuing system in order to establish the best-achievable latency distribution. Using fine-grained measurements of three different servers… CONTINUE READING
