And if each thread (ergo network connection) is busy, then the context switching to each thread can be significant.
另外，如果每个线程都忙于处理网络连接，线程之间的上下文切换会很频繁。
Modern operating systems generally do an excellent job of process scheduling, which minimizes context switching.
现代操作系统通常在进程调度方面表现得很出色，从而最大程度减少了上下文切换。
If the value of context switching is very high, increasing the time slice can improve performance, but this should only be done after extensive analysis.

Huffman suggests grouping similar processes together on the same machine or group of machines to avoid context switching all the time which consumes resources.
Huffman建议将类似的进程集中在一台机器或一组机器上，这样可以避免频繁的上下文切换，减少资源消耗。
The benefit of using the Project Explorer in this way is that the document that you are editing is always visible so that no context switching is required.
这种使用ProjectExplorer的优势在于，您所编辑的文件就会一直处于可见状态，这样就不需要切换环境了。
The scheme removes the software overheads of TCP/IP protocols and reduces the overheads of context switching and data copying between the kernel and user levels.
该方案消除了TCP/IP协议栈的软件开销，也减少了核态与用户态的数据拷贝和上下文切换的开销。
The act of passing execution is called "context switching" and its frequency varies, depending on the kernel? Configuration and the current system load.
传递执行权的行为就是所谓的“上下文切换”，传递的频率随内核的配置及当前负载而变化。
Operating systems can generally switch (context switching) faster between threads of the same process than between different process.
操作系统通常可以在相同进程中的不同线程之间更快速地切换(上下文切换)，而不是在不同进程之间切换。
The kernel maintains a context structure for all the processes in the system, information it needs for effective context switching among different processes.
内核为系统中所有的进程都维护了一个context结构体，以及要在不同进程之间有效进行上下文切换所需要的信息。
Our ruleof thumb in our books is to show the same code context two or threetimes before switching to just the snippets (although this rule variesgreatly with the type of code).
我们的经验是：把代码放在上下文中出现两三次以后，才开始只展示代码片断（虽然这条规则随不同的代码有很大变化）。
This avoids network latency and the overhead of inter-process communication, as well as context switching in the operating system, further contributing to extreme speed.
这样就能够避免网络延迟、进程间通信的开销以及操作系统中的上下文切换，从而进一步提高速度。
Switching context between users (for example, switching from admin-user to another user, and then back) multiple times has performance implications.
在用户间进行多次上下文切换(例如，从admin用户切换到另一个用户，然后又切换回来)会带来性能隐患。
Every reflective computation can be divided into two logical parts, context switching and meta-computation.
每一次反射计算可以被分为两个逻辑部分：计算流上下文切换和元行为。
The following figure shows how context switching begins to level off on a two-processor front-end server as processor usage increases.
下图显示了双处理器前端服务器的上下文切换是如何随着处理器使用的增加而渐趋平稳的。
Context-switch time is overhead; the system does no useful work while switching.
上下文切换的时间开销较重；在切换时，系统没有做有用的工作。
Ideal Deadline Monotonic algorithm has many assumptions, such as no resource sharing, no logical dependencies among tasks, no context switching overhead and so on.

The approaches for the optimization of the scheduling algorithm consist of lazy scheduling and direct context switching.
其中对进程调度进行优化的方法又分为了惰性调度以及直接进程切换两个方面。
Context Switching, is defined as changing focus and attention from one task to the other in relatively short periods of time.
在相对短的时间内，把注意力从一个任务切换到另一个任务，这就是“切换上下文”的定义。
