摘要: 利用排队论的相关知识,对计算机系统中常见的多服务员情况下的排队现象进行分析,通过理论推导、并用实际数据表明了在多服务员模式下,单一共享的排队等待队列的性能要优于多个独自的排队等待队列。

关键词: 排队论, 平均等待时间, 性能评价

Abstract: Based on queuing theory,the queuing phenomena often encountered in computer systems are analyzed.The result and data,deduced from foundational formulae,indicate that the performance of single-shared queuing model is better than that of multi-separated queuing model,when the system is of more than one server.

Key words: queuing theory, mean waiting time, performance evaluation
