Learn about the page file and its role in system performance.
I understand the fundamentals and reviewed the Linus video, but I still have a few points to clarify. The recommended page file size of 1915MB seems high, and it’s using around 4864MB—why that? My desktop rarely exceeds about 5GB of RAM, even when streaming or playing games. The VRAM was near maximum but never reached it. It appears Windows is relying heavily on the page file, which isn’t ideal. I’m curious if Windows could benefit from using slightly more RAM and reducing the page file size. I don’t mean to imply the system isn’t working, but I just want to grasp how it operates.
All active information must be read directly from RAM. The pagefile steps in when Windows senses limited system memory, relocating inactive or low-priority data there. Transferring data to the pagefile increases available space for future requests. Moving background content back to memory would force it from the pagefile to RAM, causing delays. Swapping quickly between storage and memory slows performance. A faster drive improves this, preventing the RAM from reaching full capacity and signaling you need more space.
It's odd how Windows 10 doesn't show the pagefile in Task Manager, but you can check it with meminfo. I'm running Windows 7 on a desktop with the System Monitor II extension. From what you see, I haven't used the pagefile much on a 16GB drive.
It comes from windows positioning standby memory for programs that aren't actively using it in the pagefile. I previously explained this issue, and it appears in several replies here.
I concur unless you have extremely limited hard drive space, I would let the pagefile manage itself, even with 16GB of RAM.
RAM remains intact without any data being split during program execution. When you switch between applications, the total available memory stays consistent. For instance, if your system has 1GB of RAM and you open a program using 300MB, the remaining space still exists across all programs. The system doesn’t fragment memory blocks or relocate data; it manages allocation efficiently. This behavior applies across operating systems, including Android, iOS, macOS, and various Linux distributions. To maintain optimal performance, defragmenting free space is essential. Disabling the page file can cause issues, especially when RAM usage exceeds available capacity, leading to crashes. Windows handles this automatically, prioritizing your RAM resources.
