摘要

减少平均响应时间一直是排队系统的理想目标。如果调度器知道作业大小(也就是服务时间)，则最小化单服务器队列平均响应时间的策略是SRPT(最短剩余处理时间)。即使对于作为大型系统一部分的队列也是如此，例如即时调度系统，其中作业在到达时被发送到多个单服务器队列中的一个。

Reducing Heavy-Traffic Response Time with Asymmetric Dispatching

Reducing mean response time has always been a desirable goal in queueing systems. If job sizes (a.k.a. service times) are known to the scheduler, the policy that minimizes mean response time of a single-server queue is SRPT (Shortest Remaining Processing Time). This is true even for queues that are part of a larger system, such as immediate-dispatch systems where jobs are sent to one of multiple single-server queues upon arrival.
