Windows 10: Windows Task Manager Memory resource values in percents and values do not match

I have 8GB RAM in my Windows 11 PC. The screenshot below shows that chrome is using about 800MB of RAM which is around 10% of the total RAM installed 800MB is around 10% of 8GB. But after I right click in the Task Manager window and change the Resource values of Memory from values to percents, it shows that chrome is using about 20% Memory as in the second screenshot. Why does Task Manager think that 800MB is 20% of 8GB? I am aware that Task Manager shows approximate values but approximation does not mean that values can become twice as much.I am using the latest release of Windows 11 right

How to read the CPU utilization values shown in Task Manager

Hi all,

I am trying to monitor the overall CPU utilization and show it in my application(built using LabVIEW). Most of the online search suggests using performance monitor counters but the values are way off (sometimes 30% difference) from what is displayed in Task
Manager.

I would like to understand how the Task manager computes CPU usage and is there any DLL or Command line to get that value.

Thanks,

Mani.

 

Under Memory/Performance tab in Task Manager, what does the cache value means?

In Vista and later the Cached value is the sum of the Standby and Modified lists as shown in Resource Monitor. This is RAM. The CPU cache is internal to and managed by the CPU and not shown in Task Manager. The file cache is RAM used to contain frequently accessed portions of disk files. It is not part of the Cached value and Task Manager shows nothing about it.

The Standby list is RAM and serves a dual role. It contains application data but has not been recently accessed. In fact much of it will never be used by the application again. If it is later needed the application can quickly reclaim it.

The data in the Standby list is also on the disk. This makes it possible to quickly reassign this memory to any other process that needs it. The details are complex and I will not describe them here.

The Modified list is RAM that contains data that has not yet been saved to disk. When that is done it will go to the Standby list. It's size is usually quite small, probably less than 50 MB on a 4 GB system. I will say no more about it.

Most of the Cached value is available memory and freely available to any process. This is much better than free memory which should be kept to the absolute minimum.

Cached memory is a major contributor to system performance and a high value is a good thing. Clearing it would almost always be bad idea and would negatively effect performance. Windows provides no user accessible means of doing so. There are utilities available that can do this but they are best left to those who have a thorough understanding of the implications.

As a general rule caches are best left alone. They are complex and would not have been developed unless they provided a valuable service.

I see nothing in the screenshot that would be a cause for concern.

 

Not Showing network values in task manager.

Hi Jay,

If your network adapter is rated as having a very fast maximal bandwidth such a 1 Gbps, Windows might ignore 1 Mbps as being too small a percentage to show. We suggest that you use the Resource Monitor or a Task Manager replacement.
