Windows 10 and Windows 11: optimally set the swap file – this is how it works


Under Windows 11 and Windows 10 you can trim the performance of your system with the optimal setting of the swap file. Research Snipers shows what you have to consider. Windows 10 and Windows 11 outsource seldom used areas of the main memory to the pagefile.sys swap file and use this virtual memory to create space for system components and active processes. Depending on the equipment and performance of your computer, you can specifically optimize the settings for the swap file. Because by default Windows uses an automatism that is geared more towards stability than performance. For a fast SSD with a lot of space, different settings are recommended than for an old and slow system hard drive. And if you have installed several hard drives in your computer, you can also distribute several swap files depending on the drive speed.

Typical scenarios

If your computer has a lot of fast RAM that you rarely use to its full capacity, you can completely deactivate the swap file. If the RAM is running out during operation, Windows will show you a corresponding warning message. Deactivating the swap file is also recommended if your hard drive is very slow compared to the rest of the system components. If, on the other hand, you have installed a fast SSD, you should activate the swap file for it.

If there are several SSDs installed, it makes sense to distribute the virtual memory over the individual SSDs.

You should replace the automatic size management provided by Windows for swap files with a fixed default.

The increase in the swap file that would otherwise take place during operation is a brake on performance. A good target size is the size of the built-in memory, given the available hard disk space. Computers with small SSDs with a size of 128 gigabytes are a special case. Since a fixed swap file occupies valuable storage space, you should either deactivate it there completely or, if necessary, preset it with a small initial size. The following steps show you how to make the appropriate settings.
