The CPU simply becomes overburdened by context switching between threads.

由于要在线程间进行上下文切换，因此CPU简直变成了超载。

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。

To implement a component-scoped thread pool, a third-party thread pool must be used in conjunction with the J2EE context switching capability of asynchronous beans.

要实现组件范围的线程池，必须将第三方线程池与异步Bean的J2EE上下文切换功能结合使用。

In the available literature the cost of context switching is discussed for workplace interruptions like phone calls, emails and personal requests.

诸如电话、email及个人需求等工作中断所导致的上下文切换成本在现有文献中已有所讨论。

Problems in the transport layer of TOP and their solution are pointed out. Several critical issues for implementing TOP on UNIX are discussed with details. Connection context switching technique is developed to control transport connection concurrency.

本文指出了TOP运输层协议选择中存在的问题和解决方法，讨论了几个在UNIX系统上实现TOP的重要问题：采用连接上下文切换技术来控制运输连接的并发性；

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。

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。

互联网摘选

Context switching between threads involves saving and restoring the state of threads.

上下文的转换包括了保存和恢复线程状态.

One can look at the context switching using either the vmstat or sar commands.

使用vmstat或sar命令可以查看上下文切换。

The first case is a file transfer server to verify the improved network input-output model by effect of CPU context switching.

第一个案例是服务端文件传输，用于验证改进的网络输入输出模型对CPU上下文切换的影响。

互联网摘选

Since the WorkManager instances are available in the global namespace, they can be shared amongst multiple applications and, therefore, require J2EE context switching.

由于WorkManager实例可用于全局命名空间，所以它们可以在多个应用程序之间共享，因此需要J2EE上下文切换。

互联网摘选

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。

Before changing this, make sure you run vmstat enough to determine that there really is a considerable amount of context switching going on.

在进行这种更改之前，请确保反复地运行vmstat以确定系统中确实正在进行大量的上下文切换工作。
