在本系列的第一部分^(Part)中，我们讨论了如何打开任务管理器^{(task manager)}并浏览了进程、详细信息和服务选项卡^{(Details and Services tab)}。在第二部分中，我们将介绍性能^{(Performance)}和应用历史记录^{(App History)}选项卡。

在第三部分^{(Part III)}中，我们将讨论Startup 和 Users 选项卡^{(Startup and Users tabs)}。

性能选项卡

性能选项卡^{(Performance tab)}可能是我在任务管理器^{(task manager)}中最喜欢的。它使您可以实时查看各种组件的负担情况。顶部是CPU ，当您单击选项卡时，这将是默认选择。^{(default selection)}

在右窗格中，您将看到一个利用率图表和许多有关您的处理器的有用信息。在顶部，它会给你CPU的名称，在我的例子中是Intel Core i7-8700K。在底部和右侧，您将看到基本时钟速度^{(base clock speed)}、CPU插槽数、内核^{(number of cores)}数、逻辑处理器数（如果您的CPU支持超线程）、是否支持虚拟化以及CPU的大小缓存。

在左侧，您将获得处理器的实时利用率和实时速度。您还将看到进程、线程和句柄的总数。上图中^(Above)，CPU 图表^{(CPU graph)}显示了整体CPU 利用率^{(CPU utilization)}，但如果您想查看每个单独的内核^{(individual core)}，只需右键单击图表，单击将图表更改为^{(Change graph to)}，然后单击逻辑处理器^{(Logical Processors)}。

如果单击Memory，您将获得一个图表，显示当前正在使用的内存量。顶部是系统上安装的内存总量（在我的情况下为 32GB）。

您还将获得有用的信息，例如内存速度（对我来说是 3000 MHz）、正在使用的插槽数（4 个中的 2 个）以及外形尺寸^{(form factor)}( DIMM )。左边是一堆关于正在使用的内存量以及分页和非分页内存量的技术细节。如果您想了解有关分页池与非分页池内存的更多信息，请查看^{(Paged Pool vs Nonpaged Pool memory)}Microsoft的这篇文章。

对于磁盘，您将看到系统上安装的每个硬盘驱动器的图表。就我而言，我有三个硬盘，所以我有三个图表（C、D、E）。下面^(Below)是我的系统驱动器^{(system drive)}(C) 的图表。

除了disk model/brand、读/写速度、平均响应时间和磁盘大小^{(response time and disk size)}之外，此选项卡上没有太多信息。

如果您有多个网卡^{(network card)}，您也会看到多个以太网图^{(Ethernet graphs)}。就我而言，我有两张网卡^{(network card)}，但只连接了一张。

除非您正在积极下载/上传某些东西，否则以太网^(Ethernet)图通常非常裸露。上面，我开始了速度测试^{(speed test)}，拿到截图的时候是在上传阶段。因此^(Hence)，发送值为^{(send value)}721 Mbps。值得注意的是，顶部的吞吐量值会根据使用的带宽量而变化。^(Throughput)

最后，如果您有专用显卡，您还会看到GPU 图^{(GPU graph)}。如果您有多个显卡，您将获得多个图形。卡的品牌和型号^{(brand and model)}将列在顶部。

在底部，您将获得有关已安装的驱动程序版本和支持的^{(driver version)}DirectX版本的信息。您还将获得有关专用GPU 内存^{(GPU memory)}和共享内存的信息。这些图表还按任务细分了GPU 使用情况^{(GPU usage)}：3D、复制^(Copy)、视频编码和视频解码^{(Video Encode and Video Decode)}。

这是对性能^{(Performance)}选项卡的详细介绍。与性能选项卡^{(performance tab)}相关的是应用历史记录^{(App History)}选项卡。

Windows 10 包含许多内置的Windows 应用商店应用程序^{(Windows Store apps)}，此选项卡将显示有关这些应用程序以及您自己安装的任何应用程序的信息。此选项卡仅用于查看哪些应用程序在一段时间内使用最多的CPU或最多的网络带宽^{(network bandwidth)}。单击^(Click)列标题^{(column title)}以按该列对列表进行排序。在此选项卡上您确实无能为力。右键单击只能让您切换到应用程序，如果它尚未打开，它将基本上打开它。

这就是Performance 和 App History 选项卡^{(Performance and App History tabs)}的内容。在第三部分^{(Part III)}中，我们将讨论任务管理器^{(task manager)}的最后几个选项卡。享受！

Guide to Windows 10 Task Manager – Part II

In Part I of this series, we talked about how to open the task manager and went over the Processes, Details and Services tab. In this second part, we’re going to go over the Performance and App History tabs.

In Part III, we’ll talk about the Startup and Users tabs.

Performance Tab

The Performance tab is probably my favorite in the task manager. It lets you see in real-time how taxed your various components are. At the top is the CPU, which will be the default selection when you click on the tab.

In the right-pane, you’ll see a graph of utilization and a lot of useful info about your processor. At the top, it’ll give you the name of the CPU, which is an Intel Core i7-8700K in my case. At the bottom and on the right, you’ll see the base clock speed, number of CPU sockets, number of cores, number of logical processors (if your CPU supports hyper-threading), whether virtualization is supported and the sizes of the CPU caches.

On the left, you’ll get the real-time utilization and the real-time speed of the processor. You’ll also see the total number of processes, threads and handles. Above, the CPU graph is showing overall CPU utilization, but if you want to see each individual core, just right-click on the graph, click on Change graph to and then click on Logical Processors.

If you click on Memory, you’ll get a graph showing how much memory is currently being used. At the top, is the total amount of memory installed on the system (32GB in my case).

You’ll also get useful info like the speed of your memory (3000 MHz for me), how many slots are being used (2 of 4), and the form factor (DIMM). On the left is a bunch of technical details about exactly how much memory is in use and the amount of paged and non-paged memory. Check out this article from Microsoft if you want to know more about Paged Pool vs Nonpaged Pool memory.

For disks, you’ll see a graph for each hard drive you have installed on your system. In my case, I have three hard disks, so I have three graphs (C, D, E). Below is the graph for my system drive (C).

There isn’t as much info on this tab other than the disk model/brand, read/write speeds, average response time and disk size.

If you have more than one network card, you’ll see multiple Ethernet graphs too. In my case, I have two network cards, but only one is connected.

The Ethernet graphs are usually pretty bare unless you are actively downloading/uploading something. Above, I started a speed test, which was in the upload phase when I got the screenshot. Hence, the send value is at 721 Mbps. It’s worth noting that the Throughput value at the top changes depending on how much bandwidth is being utilized.

Lastly, if you have a dedicated graphics card, you’ll also see a GPU graph. If you have multiple graphics cards, you’ll get multiple graphs. The brand and model of the card will be listed at the top.

At the bottom, you’ll get info on the driver version that is installed and the version of DirectX that is supported. You’ll also get info on the dedicated GPU memory and shared memory. The graphs also break down the GPU usage by task: 3D, Copy, Video Encode and Video Decode.

So that’s a detailed look into the Performance tab. Related to the performance tab is the App History tab.

Windows 10 includes many built-in Windows Store apps and this tab will show you info about those apps and any that you install yourself. This tab is useful only to see which apps are using the most CPU or the most network bandwidth over time. Click on the column title to sort the list by that column. There really isn’t much else you can do on this tab. Right-clicking only lets you switch to the app, which will basically open it, if it’s not already open.

That’s about it for the Performance and App History tabs. In Part III, we’ll talk about the last few tabs of the task manager. Enjoy!
