    这些单元不直接转换成时间；它们表示的是典型磁盘访问的相对时间。
16. Java Web Start will automatically determine where these files should be downloaded to, because default security protocols ( such as local disk access) do apply.
    JavaWebStart将自动决定该把这些文件下载到何处，这是因为缺省的安全性协议（如本地磁盘存取）在起作用。
17. Nevertheless, it remains a popular way to reduce disk access.
    然而，它仍是减少磁盘访问的流行方法。
18. Disk access is the slowest part of a data warehouse query, and when you need to read millions of records to get a result set for a query, the performance of your disks determines how fast you can get data back.
    磁盘访问是数据仓库查询中最慢的一部分，当您需要读取成千上万的记录来获取查询结果时，磁盘的性能决定了您获得结果的速度。
19. System Monitor enables you to see disk access and network use on% 1.
    系统监视器使您可以看到在%1上的访问和网络使用。
20. The goal of REMOCA is to reduce disk access, which is much slower than transferring memory pages over modern interconnect networks.
    由于网络传输延迟远远小于磁盘访问，用网络传输代替磁盘访问就能够有效地降低虚拟机的平均磁盘访问延迟。
