If your system has only one hard disk, you'll want to consider adding an extra hard disk. To achieve optimal paging performance, you must look at your disk subsystem configuration to determine whether your system has more than one physical hard disk. NT always places the file in the system partition's root directory, although this location is not necessarily ideal. You must consider the paging file location and size.ĭuring the installation process, NT uses contiguous disk space to automatically create the paging file. You can monitor your system's changing memory requirements and properly configure the paging file to maximize paging performance. Adding memory reduces the likelihood that the system will rely solely on the hard disk for virtual memory. One option to reduce paging activity is to add memory. To make your system run more efficiently, you must minimize the effects of paging. Accessing memory is several orders of magnitude faster than accessing the most technologically advanced hard disk drives. Hard disk access time is typically 10 milliseconds (ms), whereas physical memory access time is around 60 nanoseconds (ns).

The difference in performance between a hard disk and physical memory is astounding.
#PAGE FILE MONITOR WINDOWS 10 CODE#
When a process needs code or data that was swapped to the hard disk, the system puts that code or data back into physical memory and transfers other information to the hard disk if necessary. Paging frees up physical memory on the system and lets more processes execute. When NT starts, it creates a paging file (pagefile.sys) on the hard disk to store information. Paging is the process of temporarily transferring some of the contents of a system's physical memory to the hard disk until the system needs the contents of that memory again. Microsoft designed Windows NT to use paging for virtual memory regardless of how much physical memory is available.

It isn't an infinite well of additional yet slower memory you can call upon.LEARN HOW TO INCREASE YOUR SYSTEM'S EFFICIENCY Now, the thing is, virtual memory has its own limits. Windows 11 Is Running Low on Virtual Memory However, as your hard drive or even solid-state drive is much slower than your RAM, system performance will take a hit. When your RAM runs low, your system will call upon the paging file to handle some of the extra data. It allows your system to handle more data for more programs than previously available. So, this virtual memory is extremely useful. Your system's virtual memory does this using part of your hard-drive memory to expand your RAM effectively. Well, if you use all the RAM available to your system, it will utilize virtual memory-also known as a swap or paging file-to provide a temporary expansion. It is much faster but also more volatile, acting as a working storage area for the programs and files you have open. Your hard drive is where your operating system lives, as well as your photos, music, games, documents, and otherwise. We've previously explained virtual memory in more detail, but here is an outline to bring you up to speed.
