Tests prove that the average data transfer rate of the RAID which uses the read prefetch policy increases! by 60%, meeting the high requirement of I/ O performance in digital systems. 实验表明,采用顺序读预取策略的实际读平均数传率提高了60%,可以满足数字化系统对I/O性能的高要求。
This article improves on fair scheduling algorithm based on statistics. It retentions the maximum signal-to-noise ratio and the virtual time, and then adds users with an average data transfer rate. 本文在统计公平调度算法的基础上进行改进,保留最大相对信噪比与虚拟时间的因素,再加入用户的平均数据传输速率,三者相结合共同决定算法的调度结果。
