# 检查虚拟机 CPU 和内存使用情况

在使用虚拟机时，您可能需要查看 Mac 当前使用的内存与 CPU 容量。如果虚拟机使用太多内存与 CPU 而导致您的 Mac 应用程序运行缓慢，可轻松的减少分配给虚拟机的 [CPU 数量](/pdfm-19-ug-zh_cn/parallels-desktop-for-mac-19-users-guide/gao-ji-zhu-ti/shi-yong-xu-ni-ji/she-ding-fen-pei-ji-xu-ni-ji-de-chu-li-qi-shu-liang.md)与[内存容量](/pdfm-19-ug-zh_cn/parallels-desktop-for-mac-19-users-guide/zai-mac-shang-shi-yong-windows/you-hua-xing-neng/she-ding-fen-pei-ji-windows-de-nei-cun-rong-liang.md)。

要检查当前 CPU 和内存使用情况，请依次选择**“窗口”**和**“显示资源监视”**。

**注意：**&#x53EF;能会在[**“CPU 与内存”**&#x9009;项卡](/pdfm-19-ug-zh_cn/parallels-desktop-for-mac-19-users-guide/parallels-desktop-pian-hao-she-zhi-he-xu-ni-ji-she-zhi/xu-ni-ji-she-zhi/ying-jian-she-zhi/cpu-yu-nei-cun-she-zhi.md)上发现，虚拟机消耗的内存量高于分配给此虚拟机的内存量。这种情况很正常，因为资源监视显示的是所有虚拟机进程的内存消耗。

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.parallels.cn/pdfm-19-ug-zh_cn/parallels-desktop-for-mac-19-users-guide/gao-ji-zhu-ti/shi-yong-xu-ni-ji/jian-cha-xu-ni-ji-cpu-he-nei-cun-shi-yong-qing-kuang.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
