but have you actually tried to disable Pagefile and compare with pagefile enabled and disabled?
it's not a myth. I have been disabling pagefile for 6-7 years and I can see an immediate boost in performance with proper tweaks
yesterday, I have a VM running with 2GB of RAM with pagefile, I was always disappointed with its performance but when I disabled pagefile, I could see x1.5-2 gain in performance
disabling pagefile is unsafe for average/novice users but completely normal for someone who can manage their PCs well
disabling pagefile may not benefit gaming because they will be stored in RAM anyway unless there is a lack of memory so it's better to close all the processes before playing games to have more RAM for gaming
about boosting PC performance, they actually boost my FPS but I had to learn how to use it properly. General tweaks won't help
from me who has i7-3630QM, GT650M, 8GB who try to play FIFA18 on the lowest preset, average FPS ~30-40, sometimes 20-25
You could probably disable the pagefile without ill effects. But that doesn't make it a good idea. There is a great deal of confusion and misinformation on the Internet regarding the pagefile. Much of the confusion is based on the statement in the pagefile configuration dialog:
"A paging file is an area on the hard disk that Windows uses as if it were RAM."
While not entirely incorrect it isn't a very accurate accurate description either. Unfortunately that description is often taken far too literally, sometimes to ridiculous lengths.
The pagefile is often thought of as some kind of overflow area used when RAM runs short. There is also the widespread idea that Windows is rather stupid in it's use of the pagefile and it's size must be carefully controlled or it will be used too much. None of that is true.
At any given time there is likely a lot of memory used to store that hasn't been accessed for a long time and in fact may never be used again. Windows knows about this is considerable detail. It is a crime against performance to use high performance RAM to store what is essentially static data. The pagefile provides a place where Windows can offload this static data and making more available for more important purposes. Note that this is a highly simplified description of a very complex process with many optimizations.
The bottom line is that the pagefile will usually improve performance. Of course if you have a lot of RAM and a light workload that may not be noticeable. But except for some very unusual situations (none I can think of off hand) having a pagefile will not hurt performance.
Pagefile is like a virtual RAM, so if your usage exceed the system installed RAM than you will experience application crash or BSOD.
I don't trust none of the steps the OP youtuber linked to because it is completely bullsh*t. If you want real actual performance boost, get an SSD and upgrade your GPU. Software promise to boost your PC performance is a snake oil like registry cleaner.
