What does PF usage mean in Task Manager?

PF: PageFile (virtual memory) When the physical memory is no longer enough, put the data that is not used temporarily on the hard disk, its function is basically similar to the physical memory, and the best way to reduce the use of PF is to increase the memory.

PF usage is the amount of page files that are used by the system. If your computer is running close to its maximum, you can increase the size of the page file.

CPU usage and PF usage are proportional to your computer's CPU configuration and memory module size and system performance. If the CPU usage is too high, it means that your system overhead is too high (XP SP2) or your cup is out and needs to be replaced; The hard disk of your memory and virtual memory is PF, and "the PF usage rate is too high at startup" may be because you boot up with the system to start too many programs, and your memory is too small, or your system is not well set. o%z

Suggestion: Hardware upgrade is the best way (upgrading the memory alone will reduce the hit rate of the machine, i.e. pf down and cpu liter) wf9$

There are many ways to improve: install a smaller system, close the program that starts with boot, clear the registry garbage, do the defragmentation of the system disk, set the virtual memory and environment variables, reduce the resolution and refresh rate, and go to the control panel management tools computer management to see that it needs to manually close some system services.

Turn off the things that don't need to start when you boot up.,And go to the system process to stop some processes.,Of course, you need to be able to identify the role of each process.,It is recommended to change the fake memory to a disk other than the system disk.,This can reduce the file fragmentation of the system disk to a certain extent.,The speed can also be maintained fast for a long time.。

pf：page

file, and the page file (virtual memory) is landed.

PF Usage: The value of the amount of space that has been used by virtual memory.

This usage is not about the efficiency of memory usage, but rather about how much memory is used, so the higher the better.

CPU usage vs.

The PF usage is proportional to your computer's CPU configuration and memory module size and system performance. Too high CPU usage indicates that your system overhead is too high (XP

sp2) or your CPU is out and needs to be replaced; The hard disk of your memory and virtual memory is PF, and "the PF usage is too high at boot" may be that you boot up with the system booting the program spine sail staring too much, and your memory is too small, or your system is not set properly.

PF is the English abbreviation for page file. Refers to the configuration file of the virtual memory set by the system. Utilization is the proportion of total space used.

pf: page file, page file (virtual memory. PF Usage: The value of the amount of space that has been used by virtual memory.

There are two reasons for the high occupation of pf: First, the memory is too small, and there is really not much data in the memory, such as 128M memory to run xp Second, there are a large number of resident memory programs (str programs) and automatic loading services, many people turn on the computer, what qq, msn, bt, emule, Thunderbolt ......Open a large number of programs, these programs and services will occupy a considerable part of the memory space, resulting in a large amount of data needs to be written to the page file, resulting in high PF usage.

The best way to reduce PF usage is to increase memory.
