The closer the ratio is to100 percent, the lower the frequency of disk I/ O, and therefore the less overhead of reading data. 命中率越接近100%,磁盘I/O的频率就越低,因而读取数据的开销就越少。
As a result, the logger process frequently writes small amounts of log data to disk, with additional delay caused by log I/ O overhead. 因此,日志记录器(logger)进程频繁地将少量日志数据写入磁盘中,其中具有日志I/O开销所导致的附加延迟。
Allowing anonymous Subscribers may reduce the disk space and overhead processing required to manage Subscribers. 允许匿名预订程序可能会减少磁盘空间并减少管理预订程序的所需处理开销。
This file system adopted high efficient disk management strategies, which utilizes a disk space to serve as disk queue to reduce file manage overhead, in which adjacent messages are stored in adjacent disk block. 本文件系统一方面采用高效的磁盘管理策略,用预先分配的连续磁盘空间作为磁盘队列,消除或减少文件创建、删除等文件管理开销,并减少磁盘碎片;
Through the theoretical analysis and experiments, QLUR+-tree indexing structure can improve the efficiency of the point query and the domain queries of the entire space while maintaining a low updating cost and disk overhead. 通过分析和实验证明,该索引结构在保持较低的更新代价和磁盘开销的同时,对整个空间的点查询和域查询等具有很高的查询效率。
Disk head tracking software does not require any specialized hardware support in high-precision positioning and reducing overhead, while it achieves a variety of scheduling algorithms with a heavy load, such as the shortest access time first ( SATF) algorithm. 磁头跟踪软件不需要任何专门的硬件支持就可以实现磁头的高精度定位,降低系统开销,同时实现了能够处理大数据量负载情况下的各种调度算法,如最短访问时间优先SATF算法等。
