If you are in the IT field long enough, you have probably already heard of this rule of thumb “ page file size = RAM * 1.5 or RAM * 2“. Without a memory dump, you will not be able to do in-depth troubleshoot to get the bottom of the problems that cause your computer crash.

Without a page file or insufficient size of a page file, Windows can’t do a proper memory dump.If your computer exhausted all physical RAM and you don’t have a page file, your application will crash or hang because Windows is unable to allocate more memory.Record information about the state of the system in case of a system crash (Memory dump)īecause of these, here are the reasons why having a page file is important:.Physical extensions of RAM that stores modified data.The page file is a special file used by Windows to store modified memory pages, and the process of moving pages from RAM to the Page file is called Paging.
When the system is running low in memory, Windows will move the least used memory pages to a hidden file called the Page File. Modern Windows manages its memories based on Virtual Memory, meaning that each process has its own private virtual address space. Therefore, manually configuring the page file for your system is recommended, especially when you have tons of RAM installed. Pagefile fragmentation – if the page file expands and shrinks it can cause disk fragmentation and poor performance.Disk space – on a system with a lot of RAM installed the page file will be huge.Most of us leave it to Windows to manage to phrase out the best practice for our Windows system because, well, we all trust its expertise, don’t we? While it does allow you to run the system without worrying about the size of the page file in most situations, there are also two potential issues that are often overlooked,
The paging file is often a hot but overlooked topic that when configured properly it would not only smooth out overall the performance but also save us a lot of disk space at the end.
