平均访问时间

实验结果表明，与典型的随机放置算法和CRUSH相比，FDPA的平均访问时间更低，平均无故障时间更长。

Simulation results confirm that the average access delay of FDPA is reduced , and the mean time to failure is increased , comparing to the random placement strategy and the CRUSH method .

通过分析一个日志文件，网站管理员能找出访客总数、平均访问时间长度和最流行的目的地或网页。

By analyzing a log file , a site manager can find out the total number of visitors , average length of each visit , and the most popular destinations , or Web pages .

实验结果表明，存储系统中的热点区域一般是比较稳定的，而实现了设备间的数据动态调整后，对虚拟盘的平均访问响应时间可缩短23%。

The experiments show that the hot regions in the storage system are quite steady , and after the dynamic adjusting between devices , the average response time of virtual disks can be reduced by 23 % .

实验证明：该策略既能优化平均调谐时间，又能使平均访问时间保持在合理范围内，实现了访问时间与调谐时间之间更好的折中。

Experimental results show that the algorithm not only achieves the optimal tuning time , but also keep access time within a reasonable limit , achieved the better compromise between access time and tuning time .

存储设备／介质基本参数指标比较包括平均介质装／卸载时间、平均读写率、平均访问时间、平均数据传输率、以及驱动器／存储介质价格和系统兼容性。

Parameters comparing for storage devices / media is implemented on load / unload time , read / write time , access time , data transfer rate , price and compatibility .

索引树的结构决定了平均访问索引节点的数目，但是即使对于相同的索引结构，如果采用不同的广播序列，则平均访问时间也不尽相同。

The structure of the index tree decides the average index number to be visited , but even regarding the same index structure , the average visit time is different if the broadcast sequence is different .
