Rule Name: The paging file size should exceed the amount of physical RAM in the system.
Summary: The paging file size on some servers in the SharePoint farm is smaller than the total physical memory that is available on the servers.
Cause: A Windows best practice is to set the paging file size to equal to or greater than the total amount of available physical memory. Garbage collection is typically more effective at automatic recovery of heap memory when managed heap size approximates paging size. When paging file size is smaller than RAM size, new allocations of managed memory are granted, which leads to more garbage collection and higher CPU usage.
Resolution: Increase the minimum size of the paging file
Verify that you are a member of the Administrators group on the local computer.
In the System Properties dialog, on the Advanced tab, in the Performance section, click Settings.
In the Performance Options dialog, on the Advanced tab, in the Virtual memory section, click Change.
In the Virtual Memory dialog, select the Automatically manage paging file size for all drives check box, or clear the check box and specify a paging file size that is equal to or greater than the physical memory that is available on the computer. We recommend that you either allow the system to manage the page file size or to set it at 150% of the size of the physical RAM.
Click OK, and then restart the computer to apply the changes.

The Page File should be approximately 1.5 - 2 times the size of your total system memory (RAM). A computer with 4GB of RAM will need a Page File a minimum of 6GB (6144 MB) and a maximum of 8GB (8192MB).
You should never set that setting to 'No Page File' or set a manual amount either, you should always let Windows Manage your Virtual Memory, otherwise you either may not be able to boot up windows or you may experience many problems with software such as lagging.
The minimum and maximum size of the Pagefile can be up to 1.5 times and 4 times of the physical memory that your computer has, respectively. For example, if your computer has 1GB of RAM, the minimum Pagefile size can be 1.5GB, and the maximum size of the file can be 4GB.
Access the System Properties settings. Go to Start > Run. Type sysdm.cpl and click OK. In the System Properties dialog box, click the Advanced tab. Under Performance, click Settings. In the Performance Options dialog box, click the Advanced tab.
The Windows Pagefile is used for virtual memory operations by the Windows kernel. Windows pagefile sizes are set during installation, and normally do not have to be changed. However, if you add memory to your system after initialization, you may need to increase the “initial pagefile size” on the primary boot drive.
Navigate to “Advanced system settings” and click on the “Settings…” button in the Performance section. In the Performance Options window, go to the Advanced tab and click on “Change…” under Virtual Memory. Uncheck “Automatically manage paging file size for all drives”. Select the system drive with the large pagefile.
In the System Properties dialog box, click the Advanced tab and click Performance Options. In the Performance Options dialog, under Virtual memory, click Change. In the Virtual memory dialog box, select a drive. Under Paging file size for selected drive, type new values for initial and maximum sizes for the disk.
For systems with more RAM, you can make the paging file somewhat smaller. You could trim the paging file to 2 GB on a 16 GB system, for example, or to 3.5 GB on a 32 GB system without running into any noticeable performance problems.
Yes. You have two possibilities. One, you have plenty of RAM and you won't care if you have a page file because you won't be using it. Or two, you run out of RAM and need a page file.
As a rule of thumb, the paging file should be a minimum of 1.5 times the size of your installed RAM, and a maximum of 3 times your RAM size. For example, if you have 8 GB RAM, your minumum would be 1024 x 8 x 1.5 = 12,288 MB, and your maximum would be 1024 x 8 x 3 = 24,576 MB.
But if PC runs out of RAM and starts swapping memory between RAM and disk performance will be drastically impacted, especially with HDDs. Increasing page file size makes sense when programs use lot of memory. In Windows page file size is one defining total amount of Virtual Memory available to all running programs.
On a 32-bit system running the normal kernel, the maximum size of each page file is 4095 MB. On x64 systems and x86 systems with the PAE kernel, the maximum page file size is 16 terabytes (16TB). On IA-64 systems, each page file can be as large as 32 terabytes.
On most Windows 10 systems with 8 GB of RAM or more, the OS manages the size of the paging file nicely. The paging file is typically 1.25 GB on 8 GB systems, 2.5 GB on 16 GB systems and 5 GB on 32 GB systems. For systems with more RAM, you can make the paging file somewhat smaller.
However, with advancements in technology and more efficient operating systems, this rule is not as rigid as it once was. For a system with 16GB RAM, setting the virtual memory between 24GB to 32GB is a good starting point, but adjustments might be needed based on specific use cases.
