What is PF usage in Task Manager?
Pf Usage is “page file” usage, which is a variable amount of hard drive space that is dedicated to your total system memory. When your free RAM is low, the computer will start using this space to store RAM instructions.
Why is the page file usage high?
Your application needs more memory. The default setting allows kernel/driver files to page, freeing up more memory for your application so you application has to page less.
How do I reduce Windows memory swap?

What is PF usage?
It is how much page file space would be used if all the private committed virtual memory in the system had to be paged out all at once. The task manager ;what it calls “pagefile usage” is actually the system commit charge (the total number of committed pages in the system).
What happens if pagefile is full?
The fact that the page file is full simply means that hard page faults are occurring. It is not necessarily good or bad, other than excessive page faulting will impact performance.
How much swap usage is normal?
What Is an Acceptable Swap Usage Percentage?
| Amount of RAM in the system | Recommended swap space |
|---|---|
| <=2GB | 2 times the amount of RAM |
| 2GB – 8GB | Equal to the amount of RAM |
| 8GB – 64GB | At least 4 GB |
| > =64GB |
How do I reduce swap usage?
To clear the swap memory on your system, you simply need to cycle off the swap. This moves all data from swap memory back into RAM. It also means that you need to be sure you have the RAM to support this operation. An easy way to do this is to run ‘free -m’ to see what is being used in swap and in RAM.
Does Increasing page file improve performance?
Increasing page file size may help prevent instabilities and crashing in Windows. However, hard drive read/write times are much slower than what they would be if the data were in your computer memory. Having a larger page file is going to add extra work for your hard drive, causing everything else to run slower.
Can page file be too big?
Windows creates a Pagefile. sys file in “C” drive’s root directory, and it is used to swap data between the hard drive and the faster random access memory, or RAM. By default, this file can be up to three times the amount of RAM you currently have installed. sys can be too large for practical use.
