System and user CPU time: The elapsed CPU time consumed invoking a method.
系统和用户CPU时间：调用某方法占用的CPU时间。
The cost can be one of the following metrics: execution time per query execution, user CPU time per query execution, and system CPU time per query execution.
这里所说的成本可能是下面的度量之一：每次查询执行的执行时间、每次查询执行的用户CPU时间、以及每次查询执行的系统CPU时间。
The user CPU time is the CPU time attributed to user instructions. The system CPU time is the CPU time attributed to the kernel when it executes on behalf of the process.
用户时间是指执行普通的指令所用的时间，系统时间显然是进行系统调用，特权指令所消耗的时间。
An important goal of a scheduler is to allocate CPU time slices efficiently while providing a responsive user experience.
调度器的一个重要目标是有效地分配CPU时间片，同时提供很好的用户体验。
This test scenario compared average user response times, probe response time, system CPU utilization, memory used, and disk utilization at various loads.
该测试场景比较各种负载情况下的平均用户响应时间、探针响应时间、系统cpu利用率、占用的内存和磁盘利用率。
The actually priority of a user process varies over time, depending on the amount of overall CPU time that the process has used most recent.
用户进程的实际优先级会随着时间发生变化，这取决于该进程最近所使用的CPU 时间。
CPU time comprises user as well as system CPU.
CPU时间包括用户和系统CPU。
For example, it is better to define a Web application's policy in terms of response time to the end user instead of maximum CPU utilization threshold.
例如，定义Web应用程序策略时最好是根据对最终用户的响应时间，而不是最大的CPU使用阈值。
The "user" field tells you the sum of CPU time used by the user processor for the operation.
“user”字段告诉您用户处理器为该操作而占用的CPU时间总和。
The columns to observe are "us," "sy," and "id," which denotes CPU utilization time in user space, system space, and system idle time in percentage.
请注意“us”、“sy”和“id”列，它们分别表示用户空间和系统空间的CPU利用率百分比以及系统空闲时间。
For example, if the environment does not have a lot of CPU power and the nature of the end user requests are most likely different each time, using the Query Plan Cache would not make sense.
例如，如果环境没有大量cpu功率，且终端用户请求的性质每一次可能不同，使用QueryPlanCache就没有意义。
It can be very useful to look at the total elapsed time and compare that with the user and system CPU times.
看看总耗时，并将其与用户和系统CPU时间相比较，这样做是十分有用的。
If these tools show that your CPU is spending most of its time in user space and the idle cycles are dwindling, it is time to look at what to do next.
如果这些工具显示CPU把大多数时间花费在用户空间，空闲周期非常少，就应该考虑采取措施。
The Tprof tool is a timer profiler that identifies what code is running on the CPU during a user-specified time interval.
Tprof工具是一个计时器剖析器，可以识别出在用户指定的一个时间间隔内哪些代码在CPU上运行。
This allows the user to create stunning works in a fraction of the time of traditional CPU based renderers.
这允许用户创建令人惊叹的作品在传统的基于CPU的渲染时间的一小部分。
The task is executed only when enough idle CPU time is present at the user machine and the task runs in the background with low priority without interrupting the user's regular workload.
此任务将作为低优先级任务在后台运行，不会影响用户的正常工作负荷。如果在多个用户机器上执行多个任务，服务器将会采集并储存最终结果。
Although digital television set-top box has complete real-time operating system and CPU to coordinate and control hardware facilities in it, provides simple graphical user interface.
数字电视机顶盒虽然具有完善的实时操作系统和CPU计算能力，用来协调及制约机顶盒各部分硬件设施，并提供简易的图形用户界面。
