任务管理器中的CPU时间到底是什么？ [英] What exactly is CPU Time in task manager?

问题描述

我有一些Windows服务中托管的WCF服务。昨天我看了任务管理器，发现Windows服务进程的CPU时间超过5小时，而其他所有进程的大多数时间都为0。

I have some WCF services that are hosted in a windows service. Yesterday I looked at Task Manager and noticed that the CPU time for my windows service process was over 5 hours, while the majority of all other processes were at 0.

怎么办

我应该担心CPU时间超过5小时吗？

Should I be concerned that the CPU Time was 5+ hours?

推荐答案

CPU time 自此过程开始以来（在Windows中：链接到 Technet文章。 ）

CPU time is an indication of how much processing time that the process has used since the process has started (in Windows: link to a Technet article.)

基本上是这样计算的：

CPU Time of Process = Process Uptime * CPU Utilization of Process

的CPU利用率，例如，如果该进程已经运行了5个小时，而CPU时间是5个小时，则意味着该进程已经在使用100％的CPU资源。这可能是好事，也可能是坏事，这取决于您是想保持较低的资源消耗，还是要利用系统的全部功能。

For example, if the process has been running for 5 hours and the CPU time is 5 hours, then that means that the process has been utilizing 100% of the resources of the CPU. This may either be a good or bad thing depending on whether you want to keep resource consumption low, or want to utilize the entire power of the system.

使用50％的CPU资源并运行10个小时，那么CPU时间将为5个小时。

If the process was using 50% of the CPU's resource and running for 10 hours, then the CPU time will be 5 hours.
