增加时间切片可减少上下文切换，从而可以提高系统吞吐量。 - Finally, while the scheduling overhead of switching between threads is small, with many threads context switching can become a significant drag on your program's performance.
最后，虽然线程之间切换的调度开销很小，但如果有很多线程，环境切换也可能严重地影响程序的性能。 - 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.
如果上下文切换的值非常高，则增加时间切片可提高性能，但这必须在经过大量分析之后才能实施。 - Before changing this, make sure you run vmstat enough to determine that there really is a considerable amount of context switching going on.

由于要在线程间进行上下文切换，因此CPU简直变成了超载。 - 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。 - 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。 - Huffman suggests grouping similar processes together on the same machine or group of machines to avoid context switching all the time which consumes resources.
