1. [CPU usage]
CPU usage percentage. The bar chart shows the real-time CPU usage. 2. [CPU usage record]
CPU usage changes over time. The red line indicates the usage of the system kernel (you need to click the View menu of task manager in the red line and select "show Kernel Time ). 3. [pf usage]
PF is short for page files. This number is easy to misunderstand and is considered the size of the page file used by the system at the time. The correct description should be: the sum of physical memory and virtual memory in use. The actual page file size can be viewed using third-party software, such as pagefile monitor, or through the windows console. 4. [page file usage record]
Page file usage changes over time. 5. [total]: Total number of running handles, threads, and processes
-Number of handles: the so-called handle. Simply put, Windows identifies a long integer data that is created or used by an application, windows uses various handles to identify application instances, windows, controls, bitmaps, and GDI objects. It is a pointer.
-Number of threads: the part in the program that can run independently.
-Process count: Number of running programs. 6. [physical memory (k )]
-Total: the total amount of memory that can be viewed and touched by the sub-host. If the memory is 256 MB, that is, 256x1024 = 262144kb, the memory size of 262144kb minus the high memory size of KB, and then the 16 KB occupied by the system kernel, the actual total memory size is kb.
-Available quantity: the amount of free space that can be used by programs in the physical memory. However, the actual free space is slightly larger than this value, because the physical memory will not be switched to the virtual memory after it is used up completely. That is to say, this blank margin refers to the remaining physical memory before the virtual memory (page file) is used.
-System cache: The amount of physical memory allocated for system cache. It mainly stores some key programs and data. Once required by the system or program, some of the memory will be released, that is, the value is variable. 7. [memory usage (k )]
-Total: The total memory occupied by the operating system and the running program, including the physical memory and virtual memory (page file ). It is consistent with the above pf usage.
-Limit: the maximum amount of memory that the system can provide, including physical memory (RAM) and virtual (page file) memory.
-Peak value: the maximum amount of memory used by the system in a period of time. If this value exceeds the number of physical memory on the local machine, the physical memory should be increased to improve computer performance. If this value is close to the above "Limit, this means that you need to increase both the physical memory and the page file ). 8. [core memory (k)]: memory used by the operating system kernel and the device driver
-Total: the total number of physical memory used by the core program of the operating system. Generally, the lower the value, the better.
-Number of pages: The pages can be copied to the memory in the page file. Once the system requires this part of physical memory, it will be "mapped" to the hard disk, thus releasing some physical memory.
-Non-Paging: the memory is retained in the physical memory, which is not mapped to the hard disk, that is, the page file. Memturbo v4.1.0331 software can be used for memory management to improve the efficiency of CPU and motherboard. |
