But be careful: Don't go overboard and prefetch everything in sight, or you'll make things worse!
但是要注意：不要太过分，不要预抓取所有东西，否则会适得其反！
The Workers can be used to prefetch data or perform other ahead-of-time operations to provide a much more lively UI.
这些Workers可用于预取数据或执行其他预先操作，从而提供一个更加实时的UI。
Non-prefetch I/Os are scheduled directly from the database agents and as a result are not constrained by NUM_IOSERVERS.
由于从数据库代理程序直接调度非预取I/O，因此非预取 I/O不受 NUM_IOSERVERS 约束。
When the page scroll to about half height, prefetch the next page page content, including text, image and other object.
当网页滚动至约一半高度时，预读下一页的网页内容，包括网页文本及图片等。
Second, whenever a page is shown (see the showCities method), prefetch the next one (a logical guess) without showing it.
第二，当显示一个页面时(见showcities方法)，预抓取下一个页面(这是符合逻辑的猜测)，但是不显示它。
And finally, whenever a user picks a country and region, prefetch the first two pages just in case, as shown in Listing 4.
最后，当用户选择一个国家和地区时，预抓取前两个页面以备显示，见清单4。
For large loops, prefetch scheduling distance can be set to 1 (that is, schedule prefetch instructions one iteration ahead).
对于大循环，调度预取距离可设置为1(即，预取指令附在第一次迭代前)。
This recovery process instantly begins to prefetch dirty pages from the centralized buffer pool into its own local buffer pool.
这个恢复进程立即开始将脏页从集中式缓冲池预取到它自己的本地缓冲池。
Three basic load balance strategies on mapping applications onto GPU are presented: Prefetch, stream computing, task division.
针对GPU异构系统上的应用映射提出三种基本负载均衡优化策略：预取、流化、任务划分。
For small loop bodies (that is, loop iterations with little computation), the prefetch scheduling distance must be more than one iteration.
对于小的循环体(即有很少的循环迭代计算)，预取距离必须调度不止一次迭代。
Note that if the code asks to prefetch an already-fetched page, the implemented logic avoids making unnecessary, redundant calls to the server.
注意，如果代码请求预抓取已经获得的页面，实现的逻辑会避免不必要的服务器调用。
Based on the query pattern and the real query parameters, it developed two intelligent prefetch algorithms to fit two kinds of demand in data query.
基于这些模板和参数，提出了两种智能预取算法以适应两类不同的数据查询需求。
Even Better prefetch Paths: We made the prefetch path engine (eager loading) even smarter so it now knows more ways to optimize the queries it has to create.
更加优秀预取路径：我们设计了预取路径引擎(提前加载)更加智能以至于能通过更多的方法来优化它创建的查询。
If DB2 were to use the index the nontraditional, LIST PREFETCH way, the rows would not come back in the order of the index, but rather in the order of the table.
如果DB 2以非传统方法(LIST PREFETCH方法)使用索引，这些行可能不能以索引次序返回，而是以表中的次序返回。
The prefetch directive may be sent along with system interconnection transactions or sent as a separate transaction to devices including the target processor in the system.
该预取指令可以与系统互连事务一起或作为单独的事务发送到系统中包括所述目标处理器的设备。
When DB2 does not have an index in the appropriate order for sort avoidance or when DB2 USES any index the LIST PREFETCH way, then an order BY will most certainly cause a data sort.
如果DB 2没有一个适当次序的索引可以避免排序，或者当DB 2以LIST PREFETCH方法使用任何索引时，那么一个ORDERBY必定会引起数据排序。
Since prefetch distance is not a well-defined metric, for this discussion, we define a new term, prefetch scheduling distance (PSD), which is represented by the number of iterations.
由于预取距离不是一个明确的指标，为了讨论，我们定义一个新的术语，预取调度距离（PSD），它是由迭代的次数反映。
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。
