Task Manager Clear Cache Memory

Posted on  by admin

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. Right-click on the Start button and click on Task Manager. On the Task Manager screen, click on the Performance tab click on CPU in the left pane. In the right-pane, you will see L1, L2 and L3 Cache sizes listed under “Virtualization” section. To restart the system, right-click on the start menu and select “ Shut down or sign out → Restart “. After restarting, the memory cache should be cleared. You can see that from the task manager (CTRL + SHIFT + ESC). Clear Memory Cache by Processing Idle Tasks. Time needed: 3 minutes. On Windows 10, the easiest way to clear RAM without restarting is via a familiar tool, Task Manager. You can use Microsoft’s tool to search for hungry programs and end them. Below are images from my computer using Task Manager to show the Memory (RAM) in use. The first image shows what is cached while being used and the second is what is in use after a shutdown and reboot.

By default, Windows caches file data that is read from disks and written to disks. This implies that read operations read file data from an area in system memory, known as the system file cache, rather than from the physical disk. Correspondingly, write operations write file data to the system file cache rather than to the disk, and this type of cache is referred to as a write-back cache. Caching is managed per file object. Caching occurs under the direction of the Cache Manager, which operates continuously while Windows is running.

File data in the system file cache is written to the disk at intervals determined by the operating system. Flushed pages stay either in system cache working set (when FILE_FLAG_RANDOM_ACCESS is set and file handle wasn't closed) or on the standby list where these become part of available memory.

The policy of delaying the writing of the data to the file and holding it in the cache until the cache is flushed is called lazy writing, and it is triggered by the Cache Manager at a determinate time interval. The time at which a block of file data is flushed is partially based on the amount of time it has been stored in the cache and the amount of time since the data was last accessed in a read operation. This ensures that file data that is frequently read will stay accessible in the system file cache for the maximum amount of time.

This file data caching process is illustrated in the following figure:

As depicted by the solid arrows in the preceding figure, a 256 KB region of data is read into a 256 KB cache slot in system address space when it is first requested by the Cache Manager during a file read operation. A user-mode process then copies the data in this slot to its own address space. When the process has completed its data access, it writes the altered data back to the same slot in the system cache, as shown by the dotted arrow between the process address space and the system cache. When the Cache Manager has determined that the data will no longer be needed for a certain amount of time, it writes the altered data back to the file on the disk, as shown by the dotted arrow between the system cache and the disk.

The cache memory of RAM is a very small portion of the standard memory of your system, but the cache memory operates at a very high speed, allowing the applications/ programs to utilize its speed to run its users faster. But, sometimes due to memory leak or some bad exe files the amount of free cache memory can decrease, which eventually slows down your computer.
